Product features

ZZWP self operated temperature control valve, also known as temperature control valve, is mainly composed of a control valve and a temperature controller with fixed point adjustment. It can automatically adjust the temperature without external energy. It can be divided into heating type and cooling type according to its use. It is suitable for temperature adjustment of liquid, gas and steam as well as special occasions, and can also be used to prevent overheating or heat exchange. The valve has simple structure, convenient operation, wide temperature regulation range, fast response time, reliable sealing performance, and is widely used in chemical industry, petroleum, heating, air conditioning, and domestic hot water.
Features of self operated temperature regulating valve:
 
The self operated temperature regulating valve can work normally without power supply and air source. It uses the principle of thermal expansion of liquid and incompressibility of liquid to realize automatic regulation. The control function is proportional regulation. The nominal pressure is PN1.6, 4.0, the nominal diameter is 15-150mm, and the temperature adjustment range is 0-250 ℃. A variety of varieties are available.

Operating principle of self operated temperature regulating valve:  
The self operated temperature control valve uses the principle that the temperature sensing liquid is incompressible to achieve automatic temperature regulation. There are two types: heating type and cooling type. When the temperature of the controlled medium rises, the control valve closes (heating type); When the temperature of the controlled medium rises, the control valve opens (cooling type).
