Compatibility

Danfoss SVL Flexline FIA SS 50. This code is the straightway FIA SS 50 with socket weld (ASME B 16.11) ends and cover top. Socket-weld (ASME B 16.11), EN 10220 and ASME B 36.19M/B 36.10M weld-end preparations are not interchangeable — confirm the mating pipe schedule/OD before ordering. Shares the SVL Flexline platform with SVA-S/SVA-L shut-off, REG-SA/REG-SB regulating, SCA-X/CHV-X check valves and FIA strainers of the same nominal size.
