Recently installing TRV has become quite widespread.Some regulations are urged to ensure the presence of control valves in heating systems in order to avoid overheating, space and energy savings, as well as to be able to control the temperature and create comfortable conditions for work and leisure.

heating valve body consists of special design and to the spool shaft, which cover the working area.Adjusting the temperature control is carried out by two methods:

  • Mechanical - adjustment is carried out manually with the impact on the valve stem;
  • Auto - adjustment is carried out autonomously thanks to its special design.

In this case the valve is a thermostatic head, which contains the bellows.It is filled with gas, kerosene or a special substance.With increasing temperature, the expansion or change in the physical properties of the components, termoballon expands and pushes the stem of the bellows.This reduces the heat carrier flow and reduced energy consumption.When the air cools down, everything happens in reverse: the amount of filler in the bellows decreases, the stock returns to its previous position and the coolant flow is restored.

Before mounting the heating valve, it is important to remember a few things:

  1. It is important to position the bellows horizontally, then it will catch the right temperature.Improper installation will lead to the fact that as a result of exposure to the sensor of heat flows in different directions, the work unit is not very effective.
  2. thermostat should be positioned so that surrounding objects do not interfere with his work and that it did not fall under the direct action of heating appliances.
  3. expedient is to use a thermostatic valve and head of the same manufacturer, even if parts of different brands fit together.

Thermostatic valve to air conditioner air conditioning worked efficiently and without interruption, set thermostatic valve.Its design is slightly different from the devices for heating appliances, but the actions they have the same scheme.In air conditioning systems need to control the vapor pressure and the evaporator superheat.TRV is intended to preserve the stability of the temperature conditioning and moves the refrigerant from the condenser to the evaporator.

Types TRV for air conditioners

  1. internal adjustment - to close the valve, you need a lot of pressure and tension of the spring, and to open it - the pressure bulb, resulting from overheating of the refrigerant evaporator.
  2. equalizer - improved control scheme, allowing to maintain the stability of the system, even if the hydraulic pressure in the evaporator changes.

To the heating system in the room functioned effectively, you must be sure to install the heating valve.This will save a significant amount of energy to create the optimal parameters of the microclimate in the heated area and increase the reliability and durability of the entire system.It is recommended to choose a thermoregulatory valve Italian production, since it is the most high-quality and well-known in the domestic market.
