ZJHP type fine and small pneumatic single-seat regulating valve is composed of pneumatic multi-spring film actuator and low flow resistance through single-seat regulating mechanism. The valve body is a straight-through single-seat top-guiding mechanism without bottom cover, and the valve core is plunger-type structure. Compared with the ordinary single-seat valve, it has the characteristics of small volume, light weight and large flow. It is suitable for occasions with large flow rate and strict leakage requirements.
