Compatibility & Fitment
Danfoss SVL Flexline REG-SB 50 regulating valve. REG-SB carries the larger flow area; REG-SA is the fine low-flow variant. Select by flow direction (angleway) and connection (ASME B 16.11). Shares the SVL Flexline platform with SVA-S/SVA-L shut-off valves, SCA-X/CHV-X check valves and FIA strainers of the same nominal size.
