Self-operated Pressure Control Valve

Self-operated Pressure Control Valve
ZZYP type independent pressure regulating valve without additional energy, the use of the medium itself pressure as power source to introduce the actuator control spool position, change the pressure difference and flow at both ends, so that before the valve (or after the valve) pressure stability. It has the advantages of sensitive action, good sealing, small power of pressure set point wave and so on. It is widely used in the automatic control of pressure relief and pressure regulation in gas, liquid and steam media. This series of products have single seat (ZZYP), sleeve (ZZYM), double (ZZYN), three structures; Actuator has film type, piston type two kinds; The type of action is after pressure regulation for decompression valve (type B) and before pressure regulation for pressure relief valve (type K). The nominal pressure levels of products are PN16, 40, 64; Valve body diameter range DN20 ~ 300; There are three levels of leakage: II, IV and VI. The flow characteristic is fast opening; Pressure is segmented from 15 to 2500Kpa. Can be combined according to the need to meet the requirements of user working conditions.
