Pneumatic Actuator and Valve Packed into Single Body
Dwyer Instruments has announced the release of its W.E. Anderson series CVA compact valve and actuator, which 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. Because the actuator is part of the valve, costs are greatly reduced when compared to standard actuated valves. Balanced design reduces friction and wear, allowing the operating life to be tested to well over 1,000,000 cycles. The stroke is linear and parallel to the flow, dramatically reducing the required force to close or open the valve. The internal waterway design allows for optimum flow characteristics.

The pneumatic actuated valve can be double acting, spring return normally closed or normally open. The double acting model uses two supply ports (1/8˝ NPT) with one driving the valve open and the other driving the valve closed. Normally closed spring return pneumatic actuated models use the air supply to open the valve and internally loaded springs return the valve to the closed position. The normally open spring return model uses the air supply to close the valve and internally loaded springs return the valve to the open position. Series CVA Compact Valve and Actuators are competitively priced starting at $134.00.
