‘s Flo-Stop Valve has a reinforced stainless steel ball. The unique design of the valve allows free movement of the ball. The ball lifts out of the liquid without any interference. As the pumps 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 Linatex seal will seal.

 

The Flo-Stop is the only proven maintenance and trouble-free dewatering valve in the world, with all these features

  • Perfect sealing
  • Low head losses.
  • Non clogging, self cleaning ball.
  • Minimum back pressure for tightness: 0.3 to 0.5 bar.
  • Secondary seat (Linatex)
  • Maintenance free.
  • Full bore.
  • Silent, non-slam, reduces pipe hammer.
