Pneumatic single seat (sleeve) regulating valve

  Product overview:   Product overview pneumatic single seat (sleeve) regulating valve is composed of pneumatic multi spring diaphragm actuator and low flow resistance straight through single seat valve (sleeve valve)
The single seat valve body is straight through the guide structure on the single seat cover, and the valve core is of plunger type structure
Compared with ordinary single seat valve, it has the characteristics of small volume, light weight and large flow
It is suitable for occasions with large flow and strict leakage requirements Valve body type: straight through single seat (sleeve) inverted S-shaped cast valve nominal diameter: dn20~300mm nominal pressure: pn1
