Valve for the radiator with bottom connection

Fittings for connecting the radiators

The most common heating device in heating systems. radiator. Radiators can be selected by size, capacity, shape and even color. Today’s radiators come in so many shapes and materials that one could only dream of in the past. But any radiator by itself does not warm. It must be connected to the system. And for this use a special radiator fixture. Why do we need radiator fittings? just in order to realize a beautiful installation of the radiator in the context of the interior, while respecting the correct technical approach. After all, a radiator fixture is not just a straight faucet or an angle faucet. It is a means of hydraulic balancing, and an element of control over the temperature in the room and shut-off element as well. We offer a full range of radiator fittings for all types of radiators and convectors, for one-pipe and two-pipe systems in both standard versions. and DeLuxe series

Bottom connection of radiators

Bottom connection applicable to radiators of special design. These radiators have an inner tube that connects the connection point to the top of the radiator. To connect the radiators from below a special bottom connection knot, or as it is called by the people, binoculars. This is a compact product consisting of two shut-off valves in one casing with cap nuts for connection to the radiator. Bottom connection of the radiator is advantageous in that the width of the radiator is not added, and visually the connection knot does not catch the eye. The bottom connection can also look different. you can bring the pipes to the radiator from the floor vertically or you can connect the radiator from the wall. For this purpose the bottom angle connection has been developed.

Lateral connection of heating radiators

The classic way to connect the radiators. piping from the side. It is possible to bring the pipes from one side or from different sides. Connecting the radiators diagonally is the most effective in terms of heat transfer. You can of course connect the pipes to the radiator on one side or connect both flow and return pipes to the bottom outlets of the radiator if this is due to a particular situation or some interior design. Will work, but worse. Remember that connection of the radiator to one side reduces its efficiency compared to diagonal connection.

Thermostatic valves are used for side connection to the supply and return pipe valves. Thermostatic valves can be configured absolutely different types and shapes. They depend on the position of the supply pipe in relation to the radiator, the type of pipe and the type of connection between the pipe and the valve. The valves themselves have a connection size ½” on the radiator side, more rarely ¾”, and on the pipe side they can be the traditional female thread, 3/4″ male thread and Euroconus type, metric male thread M22, collet clamp for copper or chrome-plated tube. Therefore, the type of connection and the type of valve for the supply and return pipes are identical. They are often sold complete with a thermostatic head.

Radiator connection from the wall

Radiator connection from the wall has an undeniable aesthetic advantage. All pipes are hidden in the wall and the interior looks neater. Connection from a wall is possible for all radiators. The main thing is to be able to hide the pipes in the wall. And to pick up the fittings for connection is not a problem. There are radiator angle and three-axis valves for the connection of sectional or panel radiators in case the pipes fit from the side, and there is an angle bottom connection unit for panel radiators with bottom connection.

Bottom connection of side-vented heating radiators

There is an interesting way to connect standard sectional radiators from the floor. Such a task arises when the pipes are laid in the floor, and the radiator has a side connection. A special connection unit is used for this, consisting of a bottom unit, an upper thermostatic valve and a chrome pipe connection between the thermostatic valve and the bottom unit. This knot has all the functions to control the radiator. It also has a thermostatic element, hydraulic pre-setting and shut-off function, and even a bypass for one-pipe systems. Externally, this unit looks quite interesting, and the fitting itself is a logical continuation and decoration of the radiator.

All fittings for connecting the radiators in one-pipe or two-pipe systems are on our website. If you need advice or assistance in choosing radiators and radiator fittings, feel free to contact!

Using radiators in autonomous heating systems

If we are talking about connecting the house to a small autonomous boilers, to account for heat consumption set special counters. To use resources efficiently and not to overpay, it is recommended to install control valves in apartments during the installation of heating radiators and floor heating systems.

Different Ways to Install a Cast Iron Radiator

There are two types of shut-off and control valves. valves and valves.

When using a valve for bimetallic radiators presetting is done manually, and then the system operates automatically. The valve is regulated by a thermostatic head, which reads the room temperature. If the radiator is supposed to be installed in a recess in the wall, or there are heavy complex curtains nearby, a remote sensor is mounted for easy control of the valve.

As a rule, the radiator is connected with two shut-off valves. A valve with a thermal head is installed on top, and on the bottom. Stop valve for the radiator. Stop valve stem is usually covered with a special plug.

Please note that the shut-off valve for the bottom connection of radiators is performed only in some situations. In this regard, the stem of the shut-off valve is always raised to its maximum height, and it can be moved only with a hexagon.

Bottom connection valve for sectional radiators

Problems with radiator clogging occur when there is a very high transit flow of heat, the flute effect. For example, if on a classical Leningradka (one-pipe heating system) to run a lot of very hot coolant. the bottom tap on the radiator return should be closed. It is necessary to explain the flute effect Once we have closed the return faucet on the radiator, however it may not be a faucet but a fitting connection for the connection in which there will be a fairly narrow diameter of the inner cross section for example, the main thing that the main flow in the heating branch can capture the return flow on the principle of ejector. It is very common to get air in the radiators in a segregated connection schemes.

Why is it that with the split connection (bottom to bottom) radiators start to work as air collectors. And on, such radiators, already faucet Maevsky will be difficult to finish. You have to install an automatic air vent to permanently bleed air constantly collected in the radiators of heating.

Watch a video about the saddle or lagging of the heating branch.

Of course, the customer’s requirement can be straightforward I want to connect to the radiator lower and that’s it. But do not argue that this is not the right connection. It is better to look closely at all variants of bottom connection of radiators and understand that not all radiators connected from below are cross-sectional. For example, panel radiators have a bottom connection, which is not a saddle/left connection due to the fact that the supply in the design of the panel radiator is done from above through the hidden copper tube inside the radiator.

Typically, the connected sectional radiators in the saddle scheme that have input tubes on the sides. So in the upper connectors are twisted on one side of the plug on the other side of the Mayevsky valve and the bottom inlet and outlet.

Such a split connection will choke the battery until a special plug will not raise the flow of coolant upwards. For this we need a valve of the bottom connection of the radiator. Which not only prevents the radiator from bleeding, but also increases the heat output by 25%!

Here’s the bottom connection valve.

Its function is to completely cut off the transit flow passing through the bottom of the radiator, to redirect it to the upper area of the radiator so as to say it would not get too cold and warm well. As it is shown in the video.

The question of correct and at the same time aesthetic connection of the radiator is quite popular among those who are concerned about the installation of heating in the apartment. You might also find interesting the material on how to install the extender of the heat flow inside the radiator useful at the side connection.


There are standards for center distance at the bottom connection of radiators with bottom supply. Although perhaps not standard such as the Rifar Monolit Ventl, which is wider than its standard counterparts, which are sold in a wide range on the market

Polypropylene strappingThe cost of such work on the installation of the radiator heating in the apartment on the pipe with a jumper and shut-off cocks comes out at a price of about 2.2.5 tr. On faucets with connectors and pipes, the cost of the entire trimming will be in

Kits for radiators by connection type

Also to make a correct choice of a radiator kit you need to know what kind of connection you will have relative to the type of connection. There is a direct connection, this is when the bottom connection pipes come out of the floor. Angular connection, when the pipes come out of the wall. As a rule now in most cases the corner connection is used, as it is visually beautiful and does not take up space.

Straight sets. are used when the pipes come out of the floor, with bottom connection. With the side connection of the radiator pipes go along the wall.

Corner sets. Used when the pipe extends from the wall, with the bottom connection. With side connection when the radiator pipes come out from the wall.

Technical Information

Radiators with central bottom connection T6 are suitable for two-pipe heating systems. Radiators can also be connected to the heating system using the side connections.

Thermostatic Radiator Valves for Panel Style Radiators

The radiators are delivered ready for installation into the heating system with a pre-configured thermostatic valve for a given Kv value, corresponding to the heat output of the radiator.

When installed in a heating system with a calculated Kv value, the pre-set thermostatic valve can be adjusted to any required Kv value.

Danfoss radiator connection valve series

Danfoss thermostatic valves (cocks) are used to connect heating radiators to flow distribution systems. The thermostatic valve is mainly used to regulate the room temperature. For automatic control mode it is necessary to install a Danfoss thermostatic head. There are also valves for one-pipe heating system, shut-off valves and valves for radiator connection with bottom pipe connection.

Radiator valves can be manual or automatic. A manual radiator valve works like a valve and this enables infinitely variable control of the flow through the radiator. With a manual radiator valve, the room temperature is maintained manually. Automatic valve for the radiator otherwise known as a thermostatic valve. The thermostatic valve is part of the thermostatic radiator controller. The thermostatic valve can be used in manual mode by means of a knob. However, the main purpose of the thermostatic valve is to be used in conjunction with a thermostatic head. Thermostatic valve with thermostatic head mounted on it allows you to maintain a comfortable room temperature in automatic mode.

Radiator valves can be classified into two categories: valves for one-pipe heating systems and valves for two-pipe heating systems. Valves from both categories are designed for pump heating systems. A radiator valve designed for one-pipe heating system has a higher flow capacity. It is worth noting that the main number of radiator valves on the market are valves for two-pipe heating systems.

The radiator valve can have a pre-setting (mounting). This means that this valve incorporates the functions of both a user valve and a setting valve. Such a valve is for example a Danfoss RA-N. This valve is installed on the radiator supply.

Thermostatic control valve for radiators

Faucet and valve for the radiator heating. these are completely different units, the functions of which are different. The valve can either fully open the nominal passage or close the. Valve work is to partially block the path of coolant. This type of valve is used for regulating the temperature in the radiators and balancing the heating system.

The difference between a valve and a valve

If you enter in the search box query “valve for the radiator heating”, the output will refer to absolutely all fittings for piping batteries, starting with ball valves. But there is a conceptual difference between valves and cocks, which can’t put these two units in the same order.

A faucet is a pipe fitting that works to fully open or close the path of the heating medium. The closing element is a ball with a hole. It rotates only around its axis. There is no shift in X and Y axis.

Valves for heating radiators can partially block the path of the coolant, limiting the flow. The shutter moves perpendicular to the flow. In the upper position the nominal passage is completely open, and in the lower position, when the stop cone is lowered into the seat, the valve is closed.

In contrast to the cocks, where the ball closes the passage due to rotation, in valves is somewhat different:

The design of valves for heating radiators can be of two types: manually and automatically controlled. Manual operation is when there is no possibility to replace the rotating stem with a thermostatic head. The difference is that the thermal head does not rotate, but simply presses the slide valve due to the thermal expansion of the bellows.

Nowadays copper pipes and fittings for heating are rarely used, polymers have almost completely replaced metals.

Thermostatic valves for radiators

First we will consider the valves that, by reducing the nominal passage can regulate the temperature in the radiators. They are called thermostatic valves for radiators. As we said, there are manual and semi-automatic. Semi-automatic. because it can work in both modes.

Thermostatic radiator valves are installed on the supply. If the valve works in manual mode, then the setting is done once. Experimentally you set the desired position of the shutter cone, guided by the temperature of the batteries. The disadvantage is that as the weather changes the temperature in the room will jump. And if you have central heating, there is another unstable factor. the coolant. The degree of its heating also varies depending on the weather, this is monitored already in the boiler room.

If the thermostat valve for radiator heating is installed thermal head (if technically possible), the temperature fluctuations of the coolant and weather changes do not affect the microclimate in the room.

There is a bellows in the head. it is a capsule that contains the working substance. Due to its thermal expansion the capsule increases in volume and presses on the closing cone. In mechanical thermostatic valves the degree of thermal expansion of the medium cannot be influenced, therefore the adjustment is done by changing the distance between the bellows and the cone. In the electric heads there is a coil wound around the bellows and it heats the coil and causes thermal expansion. In this case, you can control the supply of current to the coil, respectively, influence the change in the size of the cone. Built-in temperature sensor controls this process.

Balancing valves for radiators

This type of radiator fittings is designed for hydraulic balancing of the heating system. To allow the fluid to flow evenly through all heat exchangers in the circuit, the hydraulic resistance must be balanced out.

The balancing control valve for the radiator is set according to the project. In centralized systems this work can only be done by employees of the service organization. Unauthorized intervention in the circuit is prohibited, even to change the battery without the permission of the housing and utilities committee. In small autonomous systems these valves are not necessary only if the circuit is large and has several different lengths of branches.

Balancing valves are installed in the return. that’s where the coolant leaves the battery. Come in straight and angled, it may well replace the shut-off valves (ball valves).

recently, polyethylene pipes for heating (PEH) began to be used on par with polypropylene.

For the ratio of inside to outside diameter of steel heating pipes, see here.

Combined control valves for bottom connection

There are such double valves for the radiator heating similar to binoculars. Note the presence of the cap on the side. It hides the stem to balance the system. If there is no cover, then you just have two combined ball valves. It is no longer a valve, but a shutoff valve.

Combined valves not only provide simple balancing control, they can also regulate the temperature within the radiator. For example, a four-way thermostatic knot for the bottom connection of a radiator. The installation method can also be different. There are units that work in tandem with thermostatic valves, and some that can be screwed on thermostatic head. The latter method is much more accurate.

Control valves

To adjust the optimal climate in the house on the radiators set thermostatic valves, which helps to adjust the desired degree of heating of the room by changing the flow of coolant. The shut-off and adjustment valves help to do this. These can be manually or automatically adjusted.

Balancing valves are used to link the entire heating system, which ensures that each heating element is hydraulically adjusted so that the amount of heat delivered is sufficient.

Bypass. is a spare part of pipe line, on which coolant flow is switched during repair works. It allows not to block the movement of the heating system, the liquid flows along the so-called reserve path.

Heating radiators can be connected to the mains by side and bottom connection. All depends on the location of fittings to connect the system and heating devices.
