ZMAP/ZMAN type single-seat/double-seat pneumatic membrane regulating valve

一．Product Introduction
ZMAP type single-seat pneumatic membrane regulating valve, ZMAN type two-seat pneumatic membrane regulating valve: it consists of two parts: pneumatic membrane actuator and regulating valve. It is used in conjunction with pneumatic regulators, pressure reducing valves and other instruments to control the temperature, pressure, liquid level, flow and other process parameters in the pipeline.The single-seat regulating valve has the advantages of easy sealing and small leakage, but the equilibrium force is large, so the working pressure difference should not be too high.The two-seat regulating valve has the characteristics of large flow coefficient and small unbalanced force, so it is widely used.
二.Product Features
