ZSP NC pneumatic piston at room temperature, the temperature shut-off valves, actuators and cutting machinery composed by a pneumatic piston. Press the valve sealing surface material can be divided into hard seal and soft seal: Press the valve structure type can be divided into single guide plate and single-oriented balanced. Having the structure is simple, reliable operation, tight cut off on fast and so on. Applicable to non-granule-like, no impurities gas, liquid medium, require fast tight shut, rapid emptying of the automatic control system. Technical parameters and performance I.
