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.
Valves for waste water to protect against backwater
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.
Stop Silent Light waste water valves and their advantages
Waste water valve for preventing odour nuisance from the waste water system
Nose flap (anti-frog) to prevent small animals from entering the pipes
Reliable and durable protection against backflow of water
Simple and quick installation in pipes or inspection shafts without additional work
Functionality of our waste water valves
Even with the slightest accumulation of wastewater, our wastewater valve exerts pressure on the Stop Silent Light Membrane. The membrane opens its sealing lip upwards and releases the flow for the waste water. When the wastewater flow is stopped, the sealing lip is closed and the wastewater valve closes. In order to prevent sewage gases from escaping from the cellar, for example, the rubber membrane is filled and pressed against the pipe wall during the backflow.
