AirOperated - Uses auxiliary compressed air or water pressure to shift valve, rather than a solenoid operator. ASCO offers a choice of 3 pneumatic operator pressure ratings.
Based on solenoidvalve design theory, by estimating the maximum air pressure and spring force, a direct operatedsolenoidvalve is designed to control the open and close of the air chamber.
