Red Valve Type A Megaflex

Overview:

Red Valve Control Pinch Valves offer maximum durability with precise control and virtually no maintenance. A heavy-duty, rugged pinch mechanism positions the sleeve, resulting in accurate flow control. Our Control Pinch Valves have no packing to maintain or seats to wear, no fugitive emissions and no need for expensive body alloys. Variable orifice and cone sleeves can be specified to further enhance control performance and match the exact CV level desired. True feedback positioning is accomplished through the direct linkage of the pneumatic positioner to the valve stem shaft, with no splitting of the positioner output. Red Valve Control Products are available with pneumatic, electropneumatic, or digital positioners to link up to all control systems.

Description:

The Type A Megaflex is the most economical large-diameter automatic valve available. 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. Regulating and controlling the amount of different air pressure applied into the cavern between the outside of the sleeve and inside of the valve body will open, throttle or close valve. 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.
