ZSPC pneumatic piston cut-off valve Overview:

ZSPC-type pneumatic piston room temperature, temperature cut-off valve, pneumatic piston actuator and cut off the composition of the machinery. According to the valve sealing surface material can be divided into hard seal and soft seal: According to the structure of the spool can be divided into single-oriented flat and single-guided balance. Has the characteristics of simple structure, reliable action, close, close fast. For non-particulate material, no impurities in the gas, liquid medium, requiring close close fast, quick emptying of the automatic control system.
