Introduced and patented by Red Valve, the air -actuated Type A Pinch Valve offers a unique, cost-effective solution to flow control problems.
More Red Valve Type A Valves are in use than any other Pinch Valve throughout the world.
The secret is in the rubber sleeve - the valve’s only wetted part.
Actuation of the valve is accomplished by air or hydraulic pressure placed on the sleeve.
The valve body acts as a built-in actuator, eliminating costly pneumatic, hydraulic or electric actuators.
Adding air pressure within the annular space between the body and the sleeve can open, throttle or close the valve.
