Check valves type ABS


Ensuring one way drainage systems

Check valves type ABS are non-return valves made from cast iron or plastic for horizontal or vertical discharge lines in accordance with EN 12050-4.
Main benefits
  • Silent shut-off and effective sealing
  • No flutter of the flap in the case of long pipelines (flap valve)
  • Self-cleaning effect due to the ball movement (ball valve)
  • Vertical or horizontal installation
  • Minimum head losses
  • No wearing parts
Main applications
  • Wastewater
  • Sewage


Main design features
  • Ball check valves type ABS are designed for use in drainage and sewer mains. The unique design of a ball check valve allows free movement of the ball while at the same time ensuring  a good seal.
  • The flap check valve is a synthetic non-return valve for use in drainage and wastewater mains. Its two-piece design features a single disc seal that operates on a moulded rubber hinge, which when open makes the total diameter of the pipe available for the passage of the medium.
