Backflow control valves for sewage or rainwater

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

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.
