| Description | 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.

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. |
