Danfoss REG-SB SS stainless-steel hand regulating valve. Select by nominal size (DN32 / 1 1/4 in). The SS (stainless) body is a separate range from the carbon-steel REG-SA/REG-SB; confirm the piping material and butt-weld schedule before ordering. Shares the SVL Flexline platform with the SVA-S/SVA-L shut-off and SCA-X/CHV-X check valves of the same size.
