Air Operated Pinch Valves Type A Megaflex
Air Actuated Pinch Valves offer a cost-effective solution to flow control problems. The secret is in the rubber sleeve – the valve’s only wetted part. Actuation of the valve, the pinching action, is accomplished by air or hydraulic pressure placed directly on the elastomer sleeve. The valve body acts as a built-in yactuator, eliminating costly hydraulic, pneumatic, or electric operators. The sleeve’s flexibility allows the valve to close droptight around entrapped solids. In general, 25 psi over line pressure is required for full closure of air actuated pinch valves.

The Type A Megaflex is the most economical large diameter automatic valve available.
First introduced by Red Valve, the Type A Megaflex Valve, available in sizes 20” to 84”, is extremely simple in design and principle. As with every Red Valve Pinch Valve, the elastomer sleeve is the only wearing part, drastically reducing maintenance costs. The Megaflex Valve’s full-ported actuation is accomplished by air or hydraulic pressure. The Megaflex Valve’s steel body acts as a built-in actuator, eliminating costly pneumatic, electric, or hydraulic components. Pressure within the space between the body and the sleeve can open, throttle, or close the valve. Unlike traditional gate and butterfly valve designs, there are no disks or gates to obstruct flow or create turbulence. 15 psi over line pressure will close the Megaflex.
Like all Red Valve Pinch Valves, Megaflex Valves are full ported. Thousands of dollars of savings are realized because Megaflex Valves have little head loss, substantially reducing pumping costs.
Type A Megaflex Valves are often used as effluent discharge valves controlling raw sewage, storm overflow, flow equalization, tailings in mining operations, and bulk material handling.
