The ZSPQ type pneumatic piston shut-off valve is composed of a cutting mechanism and a pneumatic piston actuator. The cut-off mechanism adopts the form of through single seat, DN20 spool is top-oriented and DN25-200 spool is double-oriented. It has the characteristics of simple structure, convenient operation, reliable use and quick opening and closing. It is mainly used in the automatic control system of liquid and gas media without impurities and particles, requiring fast and tight closure and rapid emptying.
