Pipe valves for preventing the backflow of waste water

  • Backwater valves
  • Pipe flaps
Pipe dampers from the manufacturer to prevent backflow of waste water or rainwater and as backflow protection against flooding from the waste water sewer system.

Our pipe flaps for waste water technology

Our Stop Silent SL13 check valves are designed for uncharged water up to 0.5 bar. Thanks to the simple friction clamping inside the valve, it can be quickly and easily installed in pipes for waste water, drinking water or rainwater. In addition, our non-return valves are suitable for both private and industrial customers. Stop Silent SL13 can also be used as a nose flap against the infiltration of small animals into your sewer system. When the waste water is discharged, the valve is hermetically sealed and thus prevents flooding.

Advantages of the Stop Silent SL13 tube flaps

  • Anti-reflux valve with anti-odour function
  • Non-reflux valve with nose valve function
  • Reliable and durable backflow preventer valve for sewer backflow
  • Quick and easy installation without additional work

Functionality of Stop Silent Light

With our tube flap, an accumulation of waste water exert a small pressure on the membrane. The membrane presses a sealing lip upwards and the waste water can flow. If the wastewater flow is at a standstill, the sealing lip closes and the pipe flap closes. In the subsequent backwater, the rubber membrane is filled and lies against the pipe wall. This prevents gas movement and also serves as an odour damper.
