Dual Slimline Ball Non-Return Valve (DSFFV)
Dual Slimline Ball Non-Return Valve (DSFFV)
Dual’s Slimline Valve’s heart is a reinforced Urethane or Rubber ball. The unique design of the valve allows free movement of the ball. The ball lifts completely out of the flow without any interference. As the pump stops, the ball falls and positively locates the seat due to its own weight and back pressure of the liquid. This results in drop-less sealing.
