Adjustable weir

摘要

Red Valve's Weirflex designed an adjustable syeir for storm water control in combined sewer systems. The Weirflex is a variation on Red Valve's pinch valve principal.rnThe Weirflex closes from the bottom only to create a weir that can be used to retain storm water in the sewer line. This allows the treatment plant operator to maximize existing storm water storage within the lines whilernpreventing the treatment plant from being over burdened by a storm water surge.
