The Type A Pinch Valve features a full-port opening and straight-through flow path to eliminate turbulence when open. The simple, two-piece body acts as a built-in pneumatic actuator. Fabricated elastomer sleeves are designed to offer maximum wear resistance and unbeatable sealing on entrapped debris. Double-Wall and Cone Sleeves also are available for extremely abrasive and high-pressure applications. The Type A is the original air-operated pinch valve, first patented by Red Valve in 1961.
