ZSPC pneumatic piston cut-off valve/ZSNC pneumatic piston cut-off valve consists of pneumatic piston actuator and cutting mechanism. According to the material of valve core sealing surface, it can be divided into hard sealing and soft sealing, and according to the structure type of valve core, it can be divided into single guiding plate type and single guiding balance type. The utility model has the advantages of simple structure, reliable movement, close cutting and fast closing. It is suitable for the automatic control system of gas and liquid medium without granule and impurity, which requires fast and tight closing and quick emptying.
