Dual De-Watering Flo-Stop Valve (Ddfsv)

DUAL’s Flo-stop Valve has a reinforced Stainless Steel ball.The unique design of the valve allows free movement of the ball.The ball lits out of the liquid without any interference. As the pump stops, the ball falls back and positively locates in the Stainless Steel seat due to its own weight and back pressure of the liquid.The higher the pressure the better the
secondary rubber seal will seal.
