Weirflex Valve Helps Store Water in CSO Applications

Red Valve's Weirflex(TM) creates an adjustable weir for stormwater control in combined sewer systems. The Weirflex(TM) is a variation on Red Valve's proven pinch valve principal. Instead of closing on centerline, the Weirflex(TM) closes from the bottom only to create a weir that can be used to retain stormwater in the sewer line. This allows the treatment plant operator to maximize existing stormwater storage within the lines while preventing the treatment plant from being over burdened by a stormwater surge.

The Weirflex(TM) can be controlled remotely by an electric actuator or by a handwheel and bevel gear. The open-frame construction of the Weirflex(TM) provides a visual reference to valve position and weir height. The Weirflex(TM) is available in sizes to 90"
