- Ordering Process
The ZSPQ pneumatic piston shut-off valve is composed of a cutting mechanism and a pneumatic piston actuator. The cut-off mechanism is formed by a straight-through single seat, DN20 valve core is single-directional, DN25-200 valve core is double-directional. It has the characteristics of simple structure, convenient operation, reliable use and quick opening and closing. Mainly used in impurity-free, non-particle liquid, gas medium, the requirements of fast and tight closure, rapid discharge of the automatic control system.
The product conforms to GB/T4213-92.
