Flue damper

Check valves are used in piping systems and primarily serve to prevent backflow of the medium. They can be applied to pipelines carrying various types of media. When installed in a pipeline, a check valve becomes one of the fluid components of that complete piping system. Flue gas check valves, also known as internal wall dampers, are environmentally friendly products promoted by the Ministry of Construction.

Product Description

Check valves are used in piping systems primarily to prevent backflow of media and can be applied to pipelines carrying various types of media. When installed in a pipeline, a check valve becomes one of the fluid components of that complete piping system. The flue gas check valve, also known as an internal wall vent cap, is an environmentally friendly product promoted by the Ministry of Construction and has been widely adopted in modern housing construction. The development of the flue gas check valve has solved a major challenge for new, high-end residential buildings—it not only prevents cooking fumes from flowing backward but also serves as a connection component for the ductwork.
