The Series DGV degassing valve is an all-plastic, automatic venting device designed for continuous removal of trace gases from piping systems, particularly in aggressive environments such as sodium hypochlorite or ozone systems. It features a float-actuated mechanism that opens to release gas and closes when liquid returns. The valve is installed vertically at the highest point of the system and has a 1/2" NPT connection with a 1/8" NPT vent port. Available body materials include PVC, CPVC, polypropylene, and PVDF, with FKM or EPDM elastomers. Maximum operating pressure is 100 psi, minimum specific gravity is 0.9, and physical dimensions are 4.25" high by 2.25" diameter. United States Patent #7,481,238 B2 applies to the design.
