What and how are valves used for heating?
When the heating season comes, the heating networks begin to operate at full capacity. In order to promptly intervene in their work, shut-off and control valves are provided.
With its help, it is possible to block certain areas or even contours in case of emergency situations, and also to save fuel by setting the optimum temperature in the room. Our task today is to tell about the main characteristics of these additional devices in more detail.
The normal operation of the entire heating system will largely depend on the quality of the shut-off and control valves. We recommend choosing only devices from proven manufacturers that have already proven themselves in the plumbing market. You can install it on radiators and pipelines with your own hands.
How to adjust the temperature of the coolant
Most often, as the coolant used plain or specially prepared water. Shut-off and control valves for heating makes it possible to control its temperature in the system not only qualitatively but also quantitatively.
This is more detailed as follows:
| High-quality adjustment | Changes in water temperature at the entrance to the general highway. It all depends on the temperature surrounding the device. |
| Quantitative adjustment | In this case, the flow of heated water that must pass through the system changes. The instruction allows you to increase or decrease it:

Shut-off safety and control valves
This category of devices includes:
- Ball Valves;
- valves and valves;
- pressure reducers;
- pressure and flow controllers;
- check valves;
- butterfly valves and air vent valves;
- pressure gauges;
- balancing, safety and shut-off valves;
- thermostatic fittings.
They can be installed on all elements of the heating system. On a heating device, they allow you to adjust the temperature of the coolant and protect the equipment from emergency situations. For example, when the pressure in the boiler of the heating system suddenly rises sharply, the pressure sensor will block the operation of the heat generator and begin its discharge.
Radiator
Through the use of local control valves, it is possible to regulate the heating system directly on the batteries in each room. Used for this manual or automatic valves that block or open the stroke of the coolant in the radiator. Due to this, the temperature in the latter also varies.
Tip: it is best to put valves for radiators on each device individually.
In the case of repair, replacement of the element or an accident, the heating adjustment valve will make it possible to completely shut off the water supply to the battery. We recommend that you select fittings for the heating system deliberately and without haste, especially since new products periodically appear on the market, allowing you to more effectively use the heating in your home.
Design features
For radiators use a 3-way adjusting valve of heating with a throttling device, which makes it possible to obtain a smoother adjustment. Cranes are also used with double adjustment.
Devices consist of:
- housing in which there are passages for the coolant;
- internal glass in which round cuts are made;
- spindle with handle;
- stopper.
Regulation of the flow of hot water occurs by turning the handle when the inner bronze cup begins to move up and down, due to which its cross section changes. In this way, it can completely block access to the radiator or system.
In addition to the shut-off valves on each heating line install several valves.
They are located on:
- input and output from the heat generator;
- supply lines;
- heat exchangers;
- bypass lines.
The open valve has no resistance to the flow of water.
Structurally, it consists of:
- metal case;
- control lever;
- disk shutter.
Tip: using the valve it is possible to shut off the flow in any direction, valves are designed to block the movement of the coolant only one.
Temperature adjustment
A large role in the comfort of living has the ability to control the temperature in the room. For this purpose, thermostatic fittings are provided, allowing to regulate the heating of air by automatically changing the flow of coolant passing through the heating radiator.
At its entrance a special valve is installed, which is programmable to maintain the desired temperature in the room. Regarding these values and adjustment occurs.
In most cases, all batteries today are equipped with similar devices. The thermostatic head of the equipment is programmable.
Manage her:
- mechanical - applied scale with the values of the required temperature;
- electronic - display with buttons, because of this, the price of equipment is higher, but the readings are more accurate.
It is enough to set the required temperature for the room once. In the future, the device itself will take care of it without your participation. The supply of hot heat carrier of the heating system to the radiator will be performed automatically.
Conclusion
The use of valves and control valves allows the automation to control the comfort parameters set without your intervention. It also allows you to quickly intervene in the system in case of emergencies or repairs. Installation of devices is not difficult and is done independently.
