XtraFlo


Application

Large Troughs, High Demand Compact armless diaphragm valve with full-flow high volume fill. The valve has a 25mm water level differential between opening and closing, reducing pump motor overload. Full-flow operation, the pump runs unrestricted until trough is full. Large Troughs and Header Tanks Requiring Backflow Prevention Use the adjustable arm top-entry XtraFlo valve for above water fill applications and backflow prevention. Arm length is adjustable to set water level and for greater opening and closing differential reducing pump wear
