Product Information

Application:

The valves are used in automation and contronl systems,tocontronl the pressure,flow,level,temperature,and the tank level.

Working principle:

The pneumatic stop valve can convert the energy generated by compressed the air to mechanical energy ,the merchanical energy can drive the stem axial movement ,therefore mover the sealing components in drfferent places,then can contronl the open or close of the mouth of pipe ,then achieve the purpose of change the direction of medium or keep the midum stay The manual stop valve sery operated by manualhandle ,and ultimate purpose is to change the direction of the medium or keep the medium stay .

Valve Material
