ZQGP quick disconnect valve pneumatic piston

關注次數：

ZQGP pneumatic quick disconnect valve from the domestic first introduced more than a spring piston pneumatic actuator and low flow resistance, double shut-off valve sealing structure components. Actuator movement speed, thrust, a self-reset function, with hand operated institutions; body unobstructed flow path, flow coefficient, elastic and rigid spool valve cascade double seal. New and unique structure makes the product quickly became a class action, tight cut, safe and reliable, high-performance new shut-off valve.
