DUAL DEWATERING IN-LINE BALL CHECK VALVE

DUAL'S Dewatering In Line Ball Check Valve should be isolated on the discharge side of the dewatering pump. The unique design of the valve allows free movement of the ball to open and close on reflux. Preventing the pump from turning in the wrong direction. The valve also protects the pipeline from siphoning when the pump is not in operation. There is no pressure drop across the valve.
