Adjustable weir
Red Valve's Series 53 CSO Weirflex® creates an adjustable weir for stormwater control in combined sewer systems. The unit is a variation on the company's pinch valve principal. Instead of closing on centerline, the Weirflex closes from the bottom only. This creates 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 overburdened by a stormwater surge.
