Manual Pinch Valves Series 75 Megaflex
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

Megaflex Series 75 Manual Pinch Valves are ideal for reliable operation, long life, and low maintenance. The valves are constructed with a fabricated steel body, and double acting ACME threaded pinch mechanism which closes the sleeve on centerline. Red Valve Megaflex Series 75 Manual Pinch Valves maintain a smooth venturi when closing, with no obstruction to flow. The valve is a true full ported design with no crevices or dead spots to bind valve cooperation.
Megaflex Series 75 Manual Pinch Valves eliminate packing, bearings, and shafts, so maintenance is virtually eliminated. Fully closed, Series 75’s have drop tight shut off and seal on solids. Because the flexible sleeve is the only part exposed to the line fluid, alloy bodies are not required, and maintenance of shafts and stems is eliminated. The valves break away torques always remain constant. Large diameter Series 75’s are heavy duty, maintenance free valves. Electric actuators are frequently mounted for remote operation. Series 75 Megaflex Valves are available in standard ANSI flange
