Compatibility & Fitment
Danfoss SVL Flexline SVA-S 150 steel shut-off valve. Select by direction (straightway), operator (cap) and connection standard (ASME B 36.10M Schedule 40). EN 10220 and ASME weld-end preparations are not interchangeable — the EN cell of this size is a separate code. SVA-S is the standard neck; SVA-L is the long-neck version. Shares the SVL Flexline platform with REG-SA/REG-SB, SCA-X/CHV-X and FIA of the same nominal size.
