Series VA combines a pneumatic actuator and a fast on-off control valve into one body, eliminating packing glands, actuators and mounting kits. There are no exposed moving parts, eliminating pinch points and increasing operator safety. Operating life has been tested to more than 1,000,000 cycles. The stroke is linear and parallel to the flow, reducing the force required to close or open the valve. Developed for clean media applications such as plastic thermoforming equipment, the pneumatic actuator, on-off control valve can replace angle valves and ball valves in many installations. It also can be used in place of large solenoid valves where small orifices clog and diaphragms rupture.
