ZMAP pneumatic single-seat regulating valve

Structure characteristics and application range

A
ZMP pneumatic film single-seat regulating valve, single-seat plunger spool, spool with top and bottom guide. Suitable for strict leakage requirements, before and after the valve
B
For occasions where the pressure difference is low and there is a certain year and containing fibrous media, the high pressure difference and large diameter valve should be used with the positioner.
