Product Description

Self-operated Micropressure Control Valve (ZZYP)

Summary:
Self-operated micropressure control valve adopts balanced single-seat valve with stable pressure, high precision and good tightness, which is used for controlling tiny differential pressure. It can adjust the set value at any time during operation. It can be widely applied in the medium pressure is not greater than 1.4 Mpa, the working temperature is not more than 120 ° C (150 ° C), regulating range in 0.14 to 7.2 KPa non-corrosive gas medium nitrogen sealing system of the valve after pressure.

Application:
Self-operated micropressure control valve is an energy saving product which can use the pressure of the regulated medium as power source without external energy. It is suitable for various industrial fuel gases; petroleum in process or oil storage tanks; protection gas micro pressure automatic adjustment and other occasions.

Working Principle:
The valve adopts large diaphragm actuator, the output force is large and stable, and the control precision is high. It is extremely sensitive to small changes in pressure flow. The valve core adopts single seat flow design. A balancing diaphragm is mounted on the bonnet. Compared with the regulating spring of the film actuator, when the pressure fails to reach the set value, the pressure behind the valve will increase, and vice versa.
