PQ pneumatic piston valve is composed of a cutting mechanism and a pneumatic piston actuator. The cutting mechanism with DN20 core is formed through single seat, single oriented, DN25 ~ 200 spool for double direction, has the advantages of simple structure, convenient operation, reliable use, fast switching etc.. Mainly used in without impurities and particles of liquid and gas medium, fast close, fast emptying in automatic control system.
