Pneumatic sleeve steam control valve pneumatic single seat film control valve ZJHPZJHM-16CDN251 inch

 

 

  ZJHP (M) type single seat pneumatic (sleeve) by the pneumatic spring diaphragm actuator and low flow resistance through single seat control valve (valve sleeve valve), single seat valve body through single seat cover guide structure, as the plunger type valve structure, compared with the ordinary single seat valve has the advantages of small volume, light weight, characteristics applicable to the traffic flow and so on, leakage of demanding applications. Compared with the conventional sleeve valve, ZJHM precision miniature sleeve has the characteristics of small size, 1/3, light weight, 1/3, large flow rate, 1/3, and is widely used in the industrial process automatic control system with low noise and high pressure difference.

1. This table is based on the standard specification actuator. If the maximum working pressure difference is beyond the range of the list, the factory can propose appropriate solutions.
2. This table is based on the valve position. So there is a greater allowable pressure difference at other locations.
