Sewage valves to protect against backwater from the sewage system

Sewage valves from the manufacturer to protect against backwater from the sewer system, to protect against insects and small animals from sewer systems and to protect against odours from sewer gases.

Our Stop Silent Light valve (by Lasso Technik AG) is the optimal protection against water backflow. This valve for wastewater and rainwater is characterized by its ease of installation in industrial and private water systems. In addition, quick assembly in inspection shafts or evacuation pipes is ensured by a friction clamp inside the pipe. The check valve is ideally suited for back pressure up to 0.5 bar. The Stop Silent Light water valve can also be used as a nose flap (anti-frog) by preventing small animals from entering the pipe network. In order to prevent any gas from escaping from the cellar, this valve is also equipped with an airtight odour check valve.
