Double Chamber Air Valves are used to prevent pipeline burst, as a result of air intake/discharge failure in the start-up and shut-off of the system and during operation. Double Chamber Air Valves are designed to perform three functions, which are venting of large volumes of air on the start-up of the system, while pipelines are filled; intake of large volumes of air on shut-off of the system, while pipelines are being drained; and discharge of pressurized air pockets during operation. Due to special cylindrical, full material, non-deforming float, DVD Air Valves can provide sealing even in 0.2 bar low pressure. DVD Air Valves can be manufactured from GG25, GGG40 – 40.3 – 50, GSC25, SS304, SS316 and NAB materials.
