Danfoss REG valves are angleway and straightway hand regulating valves, which operate as normal stop valves in closed position. REG-SA and REG-SB series belongs to the modular SVL product family, all valve bodies are available with different connection types and diameters. It is possible to convert a REG-SA or REG-SB series to any other product in the SVL family by replacing the all-valve train. Valves are intended for work with HCFC, HFC, R717 (ammonia), R744 (CO2), propane, butane, isobutane, and ethane refrigerants. Also available in stainless steel (REG-SA SS/REG-SB SS).
REG valves are available in two different versions – with an A cone and B cone. Model with A cone – REG-SA (S = short cap) and REG-LA (l = long cap). A cone is designed for expansion lines, and B cone is designed for flow control in a liquid line.
