self regulating valve for gas

Self-regulating pressure reducing valve engineered for purge gas service. Driven by the medium itself, its diaphragm-and-spring mechanism requires no external air, power, or controller — automatically reducing a 2.5 bar inlet to a stable 0.5 bar outlet for low-pressure purge and displacement systems. The body is ASTM A216 WCB cast steel, with 316 stainless steel seats, springs, and diaphragm cover plus PTFE disc, diaphragm, and gasket for corrosion resistance. Flanged with raised-face (RF) connections for easy installation, it accepts approved equivalents.
