ZZYV self-operated micro-pressure regulating valve belongs to the series of self-operated pressure regulating valves; it is a self-operated valve which does not need any additional energy and depends on the medium's own energy control. It is located between ZZYP and ZZYVP in the series of self-operated valves. It is mainly used in situations where the pressure before the control valve is less than 0.2 MPa.

Characteristic

1. The adjusting spring is designed on the top of the film actuator to facilitate on-site debugging.
2. Without packing, there is no friction between the upper and lower movement of the stem, and the upper seal is reliable
3. The actuator sensor is extremely sensitive, and very small pressure changes can be detected
4. The valve body is four-way, so K and B can be used as a general valve body
5. Balanced structure, not affected by pre-valve pressure
