Manual Pinch Valves Series 70
Red Valve Manually Actuated Pinch Valves are reliable, maintenance-free, cost-effective valves engineered for tough slurries, abrasives, and corrosive chemical applications. The 100% full port design eliminates any dead spots or crevices, seats or bearings where slurry can hang up and impair operation or even cause complete valve failure. Manual Pinch Valves feature bi-directional droptight shutoff in a design that meets the same face-to-face dimensions as gate, plug, and ball valves up to 12". Manual Pinch Valves employ Red Valve's state-of-the-art elastomer technology to provide smooth venturi flow, centerline closure, and excellent throttling characteristics. A number of options are available, such as the Series 75B design for buried-service conditions. AWWA nuts, chainwheels, stem extensions, and bevel gear actuators are also available

Our Series 70 Manual Pinch Valve is the counterpart to the unique Series 75 and has the same design features and advantages, but the heavy cast iron housing is eliminated and a strong fabricated steel body is in its place. The Series 70 is less costly, lighter, versatile, and can be used when the location of the valve is not exposed to attack from corrosives or other volatile material.
The Series 70 is available in the same sizes and dimensions as the Series 75. Special face-to-face dimensions are available.
The standard body material is fabricated carbon steel. Sleeve materials include Pure Gum Rubber, Neoprene, Buna-N, Butyl, Hypalon, EPDM, and Viton.
Operation of the Series 70 is the same as the Series 75, utilizing double pinch bars to compress the flexible rubber sleeve from above and below, closing simultaneously on centerline when the handwheel is turned
