Summary
The 30T02Y/30T02R self-operated temperature (cooling type )control valve is composed of the control valve and a temperature controller provided with fixed point control. It is suitable for controling differential pressure in the pipes of non-crrosive liquids, gases and steams. When the temperature of the controlled mediums rises, the control valve is opened
The main features are as follows:
1. It has the pressure balancing function with high sensitivity.
2. Low noise, reliable performance, free of maintenance
3. The standard modular design is adopted.
4. It adopts the imported fixed point controller, which has the over temperature
Protection function with reliable quality.
5. Various combined controls can be carried out through the assemblies.

Working principle
when the temperature of the controlled object is higher than the set temperature ,the liquid in the temperature controller will swell ,the force on the push of the actuator increases ,and the pulg makes the valve open under the action of the temperature controller ,the flow of water ,
or other cooling media is enhanced ,so that the temperature of the controlled object decreases ,the valve will be closed when the temperature of the controlled object decrease to the set value.after the valve is closed ,the temperature of the controlled object decreases and the valve is opened again .the cooling media enter the heat exchanger and the temperature decreased again ,so as to make the temperature of the controlled object be a constant.the opening of the valve is related to the difference between the actual temperature of the controlled object and the set temperature.
