Spiral pipe check valve with rubber seal
Check valves for spiral duct with sealing rubber
Placing a butterfly valve between a circular ventilation duct prevents the backflow of air through the spiro tube. In addition, the valve also prevents air from outside entering the spiral duct. The air pressure created in the pipe will cause the spring-back damper blades in the butterfly valve to open or close. Thanks to the rubber seal, airtightness class D (ATC 2) can be achieved and further mounting materials are not required.
Various diameters of check valves for an optimal ventilation system
This non-return valve with sealing rubber is available in various diameters and fits seamlessly on a spiral ducts of the same size. Besides being able to be placed between spiral ducts, the check valve is also suitable for placement between a pipe for the extractor hood. Like the spiro tubes, the valve is made of durable galvanised steel for a long service life and meets the strict airtightness class D (ATC 2) requirements. This back draugt shutter simply plugs into the pipe. No additional connection piece is therefore required for connection.
