What is the valve for the heating radiator. Shut-off valve for the radiator. Features of ball, valve valves with a thermostat.
Installing the screen on radiators will allow:
Make cleaning easier. Caring for radiators often causes many difficulties. The screens are an excellent protection against the accumulation of dust on the radiators, and their shape makes it easy to carry out wet cleaning. |
|
Transform view. Decorative screens will fit well into most interiors and hide radiators. All products are coated with high-quality RAL paint, which tolerates the heat of the metal structure of the screen well. |
|
Distribute warm air. The screen dissipates heat from the battery and evenly distributes the heated air in the room. The thickness of the metal wall of the screens is 0.9 mm, due to which the screen does not interfere with heat transfer. |
|
Protect children. The mobility of young children sometimes leads to bruises or burns on a hot radiator. The screen will protect the child from such injuries. |
In our store you can buy screens for radiators of different sizes. In addition, you can order the installation of a screen on a heating battery in Moscow or arrange delivery of screens to any region.
All products in our store are always in stock, so you do not have to wait long for your order. If you wish, you can pick up your order yourself at the store, which is located near the Sokol metro station.
Installed screens on the heating battery
Installing screens on cast iron batteries
First of all, it is necessary to measure the battery along the entire length or each section (from nut to nut), also measure the height and depth of the radiator. The screen sections are assembled together with fixing screws (Article: 015108 or Article: 015109) through the holes. The side ends are closed with panels, but for this it is necessary to choose a screen in width one section larger.
The design itself, depending on the radiator model, is either attached to the wall using brackets (Article: 015110) or hung directly on the battery itself.
Installation takes place quite quickly, since no additional work is required. The main thing is to choose the right screen that best suits your interior.
Installation of screens on steel batteries (accordion)
Installing these screens is easy. It is necessary to measure the length, height and depth of the radiator and thus select the desired screen size: When measuring the distance from the beginning to the end of the radiator plates, only the plates will be closed by the screen, and if from the beginning of the plates to the end of the pipe, the entire battery and its side part will be closed. You can choose a screen by height: by measuring the height of the plates (i.e. from the bottom to the top), then only the plates will close, and if you measure the distance from the bottom of the plates to the end of the fastener, then the radiator and fasteners will close with this screen.
The screen sections are assembled together with fixing screws (Article: 015108 or Article: 015109) through the holes. The side ends are also covered with panels.
The structure itself (depending on the model of the screen and the radiator) is either attached to the wall using brackets (Article: 015110), as well as using plastic clamps (Article: 015107) of the screen to the radiator case or hung directly on the battery itself.
Screens for radiators
We all strive to ensure that our home, office, any room in which we often find ourselves looking cozy and beautiful. But no matter how we decorate our interior, heating radiators, and especially old cast-iron batteries, can pretty much spoil its appearance. With their unaesthetic appearance, they immediately catch the eye, and then even a stylishly and tastefully decorated room leaves a feeling of visual dissonance and general incompleteness. However, this is not a reason to be discouraged, the ideal solution in such cases is decorative screens for batteries. Such a screen will not only hide an unattractive-looking heating radiator, but can itself serve as an element of decor. And the design of your interior will be complete and flawless.
Screens for heating radiators are made by our company from metal sheets 0.8-0.9 mm thick. Such sheets have good heat dissipation. The screen grille is painted with RAL polymer powder paint.

The word "faucet" is used when talking about different types shutoff valve. They also use taps for heating batteries installed both in apartments and taps for heating radiators in private households.
Why install taps for heating radiators
Shut-off valves perform the following functions:- it is used when a separate section of the heat supply structure is completely turned off or heater. The need for this arises when carrying out repair work or changing the configuration of the heat supply system;
- taps are used to adjust the permeability of the coolant in semi-automatic or manual mode and thereby change the air temperature in the room;
- with its help, air or coolant is discharged. In the first case, air plugs are removed from the heating system. Since the pressure drop in the structure is insignificant, if an airing occurs in the riser or in a separate section of the air circuit, water will not be able to circulate through pipelines and batteries. In another case, the coolant is dumped to flush the radiators or perform repairs.
- at the entrance of the heating main to the building. Between housing and communal services and heat supply companies there is a division of areas of responsibility, while the distinction is made where the inlet valves are located on the supply and return pipes;
- at the exit from the elevator node;
- on all heating pipes. Taps for heating radiators make it possible not to dump the entire heat supply system in the house if it is necessary to repair or replace a separate battery, since such an event is time-consuming and costly. But in a number of emergency cases, it will be faster to reset and then start heating throughout the house than to look for the necessary valves in basements and attics;
- in private housing construction, it is located on the bypass, which serves to switch the circuit from natural circulation coolant for its forced movement. To do this, you need to mount a circulation pump;
- on some heating radiators and jumpers in front of them. Often, consumers are interested in the question of why it is necessary to install taps on radiators. But the fact is that they allow you to increase the heat transfer of the device without increasing its size, due to the fact that the entire flow of liquid is directed through the radiator. But what's stopping you from just removing the jumper? And the fact that in this case it will not be possible, if necessary, to regulate the heat transfer of the batteries;
- at the top heating circuit. They can be risers connected in pairs in buildings with a bottom bottling, expansion tanks mounted on top of a supply bottling in an attic room, or top radiator plugs. In a word, taps are placed in those places where air may accumulate and must be discharged.
The right choice of control valves
When creating a heating system on your own, you need to know what types of shut-off equipment exist and which of them it is desirable to prefer:Elevator node
AT apartment buildings at the inlet and outlet of, as a rule, valves are mounted. In their body there are two rings made of corrosion-resistant steel, which encircle the passage for the coolant (mirrors). Another pair of mirrors is located on the surface of the valve - its moving part.When the damper is in the lower position and lowers, it blocks the movement of water, but if it goes to the upper position, it goes beyond the circulating flow.
To close the valve, the consumer needs to rotate the handwheel, which drives the stem, which has a screw thread. An oil seal stuffed around the stem will help ensure tightness. for heating and hot water the product must be graphite. There is no alternative to this device with a pipe diameter of 50 millimeters. It is necessary to determine which better faucets for heating radiators. If this parameter is lower, it is recommended to use modern plug valves, such as in the photo, since valves have serious drawbacks:
- it is necessary to periodically stuff the stuffing box, even when the valve is not used, since the stuffing, in contact with water, gradually collapses;
- after a short period of time, the cheeks begin to overgrow with deposits. If the valve has been idle for several years without use, it will not be possible to completely close it;
- In case of emergencies, every second can be decisive. If it takes literally a moment to close the plug valve, then it will take a long time to rotate the valve wheel, even when it is fully operational.
- practicality;
- durability;
- reliable fluid retention;
- no need for maintenance.
They have significant design flaws:
- the stuffing box will need to be stuffed periodically if there is no desire to put up with a constant leak along the stem. When it is difficult to replace the valve or stuff the stuffing box, then to eliminate the leakage, the valve must be opened to failure with little effort. The leak will stop due to the fact that the thread on the stem will press the stuffing box:
- rubber pads for elements heating structures have a limited shelf life. Radiator valves with flat brass valves do not hold water after a certain time due to deposits on the valve and seat. The same locking elements with wedge-shaped valves made of brass, after closing them with force, often wedged in the saddle;
- all screw valves are installed only in the direction of the water. For orientation, on the body of many products, a pointer is depicted - an arrow. The installation of a valve against the water inflow will certainly end with the fact that the valve will tear off and then the water will be tightly shut off.
Another undesirable prospect is associated with the operation of the valve - the possibility of water hammer if the valve is not completely closed and turbulence occurs in the water flow, periodically blocking the seat.
Water hammer- these are short-term pressure surges, as a result of which the weakest sections of the heating circuit are destroyed.
Risers and a valve that cuts off heating areas
The recommendations of experts in this case do not differ in the originality of the solution, since plug valves are considered the best choice. In the risers, it is necessary to create conditions for the discharge of the liquid coolant and plugs are chosen for this purpose, but they are not always convenient, since it will be quite problematic to unscrew the plug on the supply riser, through which a water flow with a water temperature of about 90 degrees circulates.As a result, the conclusion is obvious: valves should be installed to discharge water.
In this situation, screw devices can be used, since they will not have significant drawbacks:
- if the stuffing box is installed correctly, it will not be in contact with the pressurized water stream;
- water hammer becomes impossible, since the valve is mostly closed;
- you don't need to reset the whole house system to change the gaskets, just stop the riser.
Installation of air vents
A typical faucet for a heating battery is Mayevsky's product. The valve is a simple design of a brass rod, in the closed position, blocking the hole in the seat, and threads to install it in the radiator plug.Such taps for heating radiators are reliable and rarely need repair or replacement, but:
- their permeability is small. If you put the tap on the riser and wait about 10 minutes once a year until the air comes out easily, then a similar air vent will expansion tank apartment building it is hardly worth installing with top filling. It is better to give preference to a conventional valve;
- when buying a Mayevsky faucet, you need to choose a product for a screwdriver, and not for a special key, which is not always easy to find before starting the heating;
- part of this type of product allows you to unscrew the stem completely, unfortunately, such cases are not uncommon. No one has yet succeeded in screwing the rod into place, while overcoming the resistance of the hot coolant.
When such a tap is installed on a heating radiator, you need to remove the handle and lamb from the valve, as a small child in the house will be attracted to a bright object, and he will eventually try to turn it. The consequences will be bad.
Flush taps
Welding flushing taps can be purchased at any specialty store. They consist of a steel body, a long stem and a rubber gasket and have a decent appearance. They are opened with pliers or a gas key.But it should be noted that a flushing valve for a heating radiator is nothing more than a radiator plug or an adapter plus a plug valve. During the flushing process, the rubber gasket may be destroyed, and in the future it will not be possible to do without disconnecting the risers in the basement.
Valves that regulate the temperature of the batteries
Control valves for heating radiators are of the following types:- standard;
- with thermal head.
The adjusting tap on the heating radiator will maintain a comfortable temperature regime in room. The thermostat is mounted on the supply line of the supply pipe in such a way that the temperature-sensitive element is not heated due to the upward flow of hot air masses.
A throttle is considered a cheaper option, but it must be manually adjusted depending on the required degree of heating of the premises in the house, which of course is not very convenient. After all, both the radiator and the rooms have great inertia: the air temperature can only stabilize after a few hours after the throttle patency is changed.
Also, to regulate the movement of the coolant through the supply pipe, a conventional plug valve is used. In principle, it is not intended for this, but with its help, configuration is possible.
Heating experts advise:- screw valves for adjustment are not suitable for shut-off valves, since after a short time the valve will certainly come off or collapse;
- need to purchase couplings Ball Valves for heating radiators;
- to adjust the permeability heating battery a fully open bypass is required;
- it is advisable to put another valve on the second supply line, which, in the closed position, completely cuts off the heater, after which the radiator can be removed for repair.
Radiator taps are widely used to connect the heating pipeline to the battery. it shut-off valves, which allows you to control the flow of hot water or turn off the damaged section of the line. Also, its task is to discharge the coolant and prevent the appearance air locks. Ordinary ball valves can only be in the “open / closed” position and are not recommended for tapping into a heating system, while special locking devices(having a similar design) allow you to smoothly control the process of circulation of the coolant and contribute to more efficient heat transfer.
In fact, such products are shut-off and control valves that are maximally protected from corrosion. The material is brass (sometimes with the addition of lead) or high-quality propylene. In the first case, the radiator tap is attached to a threaded fitting, in the second, welding is used. From above, the metal is covered with a protective layer of chromium or nickel (by sputtering). The part that regulates the flow of the coolant is called a thermal head, it is characteristic only for taps of this type. Appearance and design look aesthetically pleasing; devices are installed:
- On risers in apartments with centralized heating, in order to divide into sections for sequential repairs.
- On bypasses - to switch the pump.
- Near the heating radiator, for easy dismantling and repair.
- At points of possible accumulation of air.
Depending on the method of controlling the flow of the coolant, there are:
- conventional control valves for the radiator;
- devices with a thermal head (they are also called thermostatic);
- models with a thermostat for heating batteries.
1. Control valves.
They, in turn, are divided into straight and angular types (mounted depending on the supply of coolant). This design allows you to adjust the flow rate exclusively manually, which is not always convenient. The taps are hermetic, they do not allow leaks, and most importantly, they protect heating radiators from hydraulic shock when filled with water. They do not have a temperature determination scale, the setting is performed with an error. Conventional radiator control valves are best used when assembling individual system heating. Although their appearance is quite aesthetic, which is why they look good in the office.
2. Devices with a thermostat.
Control over the flow rate of the coolant in this case is carried out using:
- Conventional two-mode ball valves.
- A cone valve that allows you to leave the valve in an intermediate position. A slight disadvantage is the manual reset and the need to keep track of the current one.
- An automatic thermostat mounted in a hole in front of the heating radiator.
The principle of operation of the taps is based on changing the permeability of the coolant entering the radiator, depending on the temperature in the room. Their tie-in contributes to energy savings and allows you to create local zones with the desired heat transfer. Thermostat taps are installed in one or two-pipe system heating, in the first case they cannot be mounted without bypasses.
3. Thermostatic radiator types.
These are temperature control devices. The thermal head is a ring with a sensitive element that reacts to thermal fluctuations and changes the amount of flow inside the heating circuit. Available in manual and automatic versions. In the first case, the temperature changes independently, in the second - autonomously: when a certain value is exceeded, the siphon with liquid increases its volume and changes the position of the stem. Installation is permissible both in one- and two-pipe heating systems, thermostatic devices are suitable for any connection scheme: side, bottom, diagonal.
Such taps and valves for radiators are cost-effective, despite the high cost. They independently maintain the parameters of the heating system at a given level, protect batteries from freezing and reduce gas consumption, therefore they are especially relevant for private houses. But accurate tracking requires accounting certain conditions operation, namely: taps with a thermal head are not closed by furniture or other materials, plus direct Sun rays. If these conditions are not feasible, then it is worth buying another type of valve for the heating radiator.

During installation modern system heating can not do without shut-off and control valves. Cranes are installed in the places of boiler piping, water drain, air bleeding, bypass installation, circulation pump, heating radiators, etc. They are designed to regulate the flow of water and shut it off in the event of a breakdown or replacement of some devices or elements in the heating system. Even the most balanced, perfect and reliable home heating scheme requires at least one tap installation - to drain the coolant. In reality, there should be much more locking elements. And what functional responsibilities each faucet will have depends on its location in the heating system; structurally, they can also differ from one another.
Important! Many faucets are marked with an arrow on the body, which indicates the direction of fluid flow. Inconsistency of the connection with the indicator can lead to breakage or malfunction of the locking device.
The basic principle of operation of any faucet is to lock and regulate the flow of fluid. This can be done using several types of mechanisms that were used in the construction of cranes and gave them names. Each type of locking and adjusting device has its own advantages and disadvantages, allowing you to better match them to a specific place in the heating system.
Each tap, even fully open, is an additional resistance in the path of water flow, which reduces the pressure and pressure of the coolant, and also requires an increase in the power of the circulation pump.
The most popular types of taps for the heating system by design and purpose:
Features of American cranes
The scheme for connecting pipes using a threaded fitting, a gasket and a union nut, which has received the slang name "American", is better in many aspects of connecting shutoff valves than using a squeegee with a number of additional components (threads, couplings, locknuts and counter threads). Also, with the old connection method, it was very often necessary to rotate the pipe or tap. Now this problem is gone. The "American" is especially effective during the installation or replacement of radiators, heated towel rails, meters, expansion tanks and other components of the heating system. And you can not do without it in hard-to-reach, inconvenient places where it is impossible to make a welding joint. To replace, dismantle or install any device included in the heating system, it is enough to turn the handle or valve to the “closed” position to block the coolant flow, and you can unscrew the union nut with a wrench, freeing any node. From the foregoing, we can conclude that the "American" is not so much a crane as a scheme for connecting pipe parts and elements. This scheme can be used in any type of valves, but most often the "American" is connected to a spherical design. It is also often possible to meet an American with a three-way valve equipped with a valve and equipped with an electric drive.
Important! There is an angular version of the "American", which has the same principle of operation as the usual one - straight.
Features of thermostatic valves
The principle of operation of mechanical, electronic and electric thermostats is the same. They operate a valve that regulates the flow of coolant through the radiator. Thermal sensors of electronic faucets are placed far beyond the body, and measure the air temperature in those places of the room that are of interest to the consumer. In this they are better than mechanical and electrical, which determine the temperature environment in close proximity to the heater. Also electronic system allows you to control the temperature remotely, using a server.
The radiator crane is one of kinds of shutoff valves. Such devices allow you to regulate the flow of coolant into the batteries by increasing or decreasing the water flow. In addition, they connect pipes to heating appliances.
Such devices allow you to regulate the temperature in the room, remove air from the system, which does not allow water to circulate and reduces the efficiency of heating the room, and also discharge the coolant.
These products are of different types. To figure out which cranes are best for you to put in your case, you should study their main properties and scope.
adjusting
The control valve for the heating radiator can be angled and straight. It is used to control the flow of coolant manually, makes it possible to prevent leakage.
Has its advantages:
- when filling the system there is no water hammer;
- allows you to remove the battery without completely shutting down the system;
- has high tightness, has an aesthetic appearance and excellent hydrodynamic properties. But it is worth remembering that such a product does not allow you to fine-tune the heat transfer, since it does not have a temperature scale.
with thermal head
There is a ring on the thermal head, limiting or blocking temperature increase. The sensitive element located inside it, during thermal fluctuations, increases or decreases the strength of the water flow in the heating system.
There are two types of thermal heads:
- With manual adjustment : manually rotated;
- with automatic adjustment: equipped with a bellows with a liquid that changes volume when heated and presses on the stem.
Such products also have their advantages:
- Ease of use because they allow you to independently regulate the temperature;
- economy: the valve makes it possible to reduce fuel consumption by limiting the temperature increase;
- the presence of a regime frost protection.
With thermostat
The thermostat is installed in a special hole in front of the radiator. Allows you to regulate the flow of water thanks to a tap mounted in front of the thermostat.
To adjust the temperature, you can use:
- ball valve: such taps are not very suitable for heating radiators, since they have only two modes: closed and open;
- cone valve: more optimal due to the presence of an intermediate position, but it must be constantly monitored and returned to its original state;
- automatic regulator: the most reliable and convenient.
When the air temperature in the room changes, the content of the faucet thermostat expands or contracts, which leads to a decrease or increase in heat transfer. This makes it possible to save fuel, set a certain temperature.
But such a system also has disadvantages: equipment selected strictly individually, and on single pipe systems need a bypass.
Mayevsky crane
Needed to bleed air from heating radiators, forming a plug. This device is very reliable rarely needs to be repaired or replaced. It is equipped with a thread, thanks to which it is installed in the battery plug.
AT modern models the stem is turned with a screwdriver. But there are instances that close and open with a special key. It is advisable to refuse to purchase them, because the key is easy to lose.
When purchasing a Mayevsky crane, you need to make sure that stem does not fully unscrew. If this happens when flushing the radiator, it will not be possible to return the part to its place, and then it will be necessary to turn off the riser completely.
Radiator taps must be optimally matched to rather difficult operating conditions:
- The water temperature in the battery is up to 200 °C.
- The pressure can reach 16-40 bar.
- Resistant to corrosion and mechanical wear is required.
Devices should be purchased specifically designed for heating systems . Other shut-off valves should not be used, as they will quickly fail.
In principle, it is quite possible to install on radiators common ball valves. It is better to choose coupling devices with threaded edges. It allows you to securely fix the valve on the radiator.
Control taps fit for systems autonomous heating , so they should not be used in apartment buildings. Devices equipped with a thermal head can be used on one- and two-pipe systems.
Of course, products with a thermostat they are more expensive, but they are much more convenient, because they allow you to create the right temperature in the room and achieve optimal comfort. It is advisable to choose an automatic thermostat.
Every person wants the highest quality, efficient, economical radiators to be installed in his house. Let's try to figure it out.
Choose a radiator, then it will be useful for you to read about specifications, and radiators.
Installation Features
Since pipes with a small diameter are usually used in residential buildings, taps are mounted using threaded connections. It is considered the best compound, called in everyday life "American".
The armature has one or two union nuts. Each of them covers the connecting shank. The nut easily rotates around it. It must be screwed onto the pipe, while pressing the tap against it. The end of the pipe must rest against the gasket laid inside the faucet.
Installation of a faucet for a heating radiator with an "American" is much easier to perform than on a coupling connection. In this case, the valve can be located near the wall.
To disassemble such a connection, you just need to unscrew the nut on one side. This will enable remove radiators for repair or gain access to the wall located behind them, without turning off the entire riser.
Replacing the tap on the "American" is also simple. Almost all "Americans" look like a hexagon, so they are installed with an ordinary wrench. But there are models where the nuts have two protrusions. For them need a special key.
When installing the device for the first time all threaded connections do not compact. This allows you to determine whether the parts fit well together. Subsequently, it will be easy to understand how much sealing material is required for each of the joints.
If the seal is not enough, there will be a leak, and its excess sometimes leads to damage to the nut when tightening, which is undesirable, because then the entire part will have to be replaced.
Connection sealing methods
If the thread does not have a sharp edge, FUM tape is suitable for sealing. But experienced professionals recommended to use linen. You need to take a thin strand, twist the bundle and wind it around the pipe, starting from the end.
The direction of the seal winding must be opposite to thread direction. Linen should fill the thread to its full depth, and each new turn partially closes the previous one. Then the connection will be strong and reliable.
If the faucet is chosen correctly and made of quality materials, it will last a long time and allow you to maintain the temperature in the room at the right level.
It is important not only to know which taps to put on heating radiators, but also to take into account the features of the operation of the product and carefully study the recommendations of the manufacturer, then the device will not cause complaints when used.
