- Ordering Process
ZZY self-operated pressure regulating valve does not need additional energy. It uses the energy of the regulated medium itself as the power source, introduces the actuator to control the valve core position, changes the pressure difference and flow at both ends, and makes the pressure in front (or behind) of the valve stable. It has the advantages of sensitive action, good sealing and small fluctuation of pressure setting point. It is widely used in automatic control of gas, liquid and steam medium pressure reduction and pressure relief and pressure stabilization.
This series of products have single seat (ZZYP), sleeve (ZZYM), double seat (ZZYN) three structures; the actuator has film type, piston type two; action type with pressure relief valve after pressure regulation (type B) and pressure relief valve before pressure regulation (type K). The nominal pressure grade of the product is PN16, 40, 64; the valve body diameter range DN20-300; the leakage grade is grade II, grade IV and grade VI; the flow characteristic is fast opening; the pressure is regulated from 15-2500 kPa. It can meet user's requirements according to needs.
Characteristics of self operated pressure regulating valve
Self-powered pressure regulator can work in a place without electricity and gas without additional energy, which is convenient and energy-saving.
The pressure range is fine and intersecting, and the adjustment precision is high.
The pressure setting value can be continuously set during operation.
For pressure adjustment after valve, the ratio between front pressure and back pressure is 10:1~10:8.
Rubber diaphragm type detection, actuating mechanism has high detection accuracy and sensitive action.
The pressure balancing mechanism is adopted to make the control valve sensitive and precise.
