Backflow control valves for sewage or rainwater

  • Backwater valves
  • Backflow Control Valves
Backwater valves for wastewater or rainwater with anti-odour function and as flood protection from the sewer pipe system.

Our backflow control valves for waste water applications

Discover our Stop Silent Light check valve for private or industrial use. Our check valves can be easily and quickly installed in existing inspection shafts and drainage pipes. The non-return valve is designed for charged water up to 0.5 bar. In order to avoid the escape of sewage gases from the wastewater system to the sewer outlet, the waterproof membrane also acts as an odour blocker. Another advantage of the valve is its nose valve function. The infiltration of small animals into your sewer system is then reliably and permanently prevented.

Advantages of our Stop Silent Light backwater valves

  • Non-return valves to secure pipelines against backflow
  • Non-return valves to prevent small animals of all kinds from entering the ducts
  • Our non-return valves also act as odour stops
  • Easy installation in your sewer system without additional work

Functionality of Stop Silent Light

Lasso Technik AG check valves block the pipe wall with a waterproof rubber membrane that opens only under the pressure of flowing water. This action is due to an accumulation of water on the membrane, which opens its sealing lip upwards. The wastewater flow can flow freely. If the wastewater flow stops, the sealing lip closes and the wastewater pipe is sealed again.
