Compatibility & Fitment
Danfoss SVL Flexline SVA-S SS stainless shut-off valve. This code is the straightway SVA-S SS 20 with butt weld (ASME B 36.19M Schedule 40) ends and cap. Confirm line size (20 mm (3/4 in)), connection type/standard, direction (straightway) and refrigerant before ordering. EN 10220 and ASME weld-end preparations are not interchangeable — the EN cell of this size is a separate code. Shares the SVL Flexline platform with REG-SA/REG-SB regulating valves, SCA-X/CHV-X check valves and FIA strainers of the same nominal size.
