Red Valve’s large-diameter Type A Megaflex Pinch Valve is ideal to handle stormwater overflows. The Megaflex offers full-port opening, no moving parts, no external actuator and the ability to close drop-tight on entrapped solids. The elastomer sleeve is the only wetted part. This 72-inch Megaflex valve is one of three installed in a major Midwestern city using the sewer system for stormwater storage. Available in sizes from 30 to 96 inches.
Red Valve's Series 5200 Control Pinch Valve is designed to provide accurate, repeatable control of abrasive and corrosive slurries. The resilient elastomer sleeve produces a smooth venturi flow path that outlasts gate, plug, ball and even stellite-coated control valves. The reinforced elastomer sleeve is the only wetted part of the valve, eliminating the need for packing, valve seats and mechanical parts. A cone sleeve trim is most commonly used in throttling applications for tighter control and better rangeability. A broad choice of controls is available -- including pneumatic, electro-pneumatic and the latest "smart"positioners.
