Air-operated pinch valve

March 30, 2003




The Type A pinch valve is the original pneumatic pinch valve, first patented in 1961. Consisting of a two-piece body and an elastomer sleeve, the Type A features a full-port opening and straight-through flow path to eliminate turbulence when open. Fabricated sleeves offer maximum wear-resistance and unbeatable sealing on entrapped debris. Red Valve Co., Inc. 700 N. Bell Ave., Carnegie, PA 15106. Tel.
