The 30T01Y 30T01R self-operated temperature (heating type) control valve

Summary

The 30T0 1Y/30T01R self-operated temperature （heating type ）control valve is composed of the control valve and temperature cont roller 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 closed

The main features are as follows:

1.It has the pressure balancingfuncti on 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 lower than the set temperature, the liquid in the temperature sensor will contract, the force acted on the push rod of the actuator decreases, and the plug makes the valve open under the action of the spring force. The flow of steam, hot oil and other heating media is enhanced, so that the temperature of the controlled object rises. The valve will be closed when the temperature of the controlled object rises to the set value. After the valve is closed, the temperature of the controlled object falls and the valve is opened again. The heating media enter the heat exchanger and the temperature rises 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.

Difference between actuator T06 and T17

The T06 model temperature sensor is isolated from the controlled medium through the temperature sensor sleeve, i.e., it does not contact the medium and it is easy to maintain. But the response is slow. It is suitable for controlling liquid media. The T17 model temperature sensor directly contacts the controlled medium, and the temperature sensing area is large. Therefore the response is fast. But it is not easy to maintain. It is suitable for controlling gas temperature and liquid temperature.
