Spiral pipe check valve without rubber seal

Backward valve for spiral pipe in your ventilation system

Placing a butterfly valve between the spiral pipe ventilation duct is recommended to prevent backflow of air through the spiral pipe. Besides the fact that the non-return valve can be placed between spiral pipes, it is also suitable for placement between a spiral pipe in front of the extractor hood. As a result of the air pressure created in the galvanised tube, the springback valve blades in the butterfly valve will open or close. The installation of a non-return valve in the galvanised spiral pipe not only optimises the air supply, but also prevents air from outside entering the spiral pipe. Like the spiro or spiralo pipes, the valve is made of durable galvanised steel for a long service life and meets the strict air tightness class D requirements. You insert this spiral pipe attachment into the tube. No additional connection piece is required for the connection.
