Odour dampers for protection against sewer gases

Smell flaps for protection against sewer gases from the sewage system and as backflow protection for sewage from the sewer system.

Our anti-odor valves for waste water networks

An important function of our check valve is the so-called anti-odour flap. When bad odours emanate from the sewer, our Stop Silent Light valve is quickly installed and reliably solves this problem. This problem occurs especially in summer when the sewage disposal system warms up and the unpleasant smell spreads into the cellar and garage. Channel gases reach the surface through inspection wells due to a so-called stack effect. In addition, our anti-odour valve provides reliable protection against backflow with a back pressure of up to 0.5 bar. Another function of this non-return device is a nose flap, preventing small animals from entering the sewer system.

Advantages of the Stop Silent Light odour valve

Valve to secure the pipes against water backflow
Anti-frog valve to prevent vermin from entering the pipe
Longer life than standard
Simple and quick installation without additional work

Functionality of our odour valve

To prevent sewage gases from escaping from the pipe system, our anti-odour flap is perfectly sealed. In the event of water backflow into the pipe, the rubber membrane is filled and pressed against the pipe wall. A slight accumulation of waste water causes reliable pressure on the membrane, the sealing lip then opens upwards and releases the waste water flow. When the flow stops, the sealing lip is restored, closing the odour check valve.
