Danfoss SVL Flexline CHV-X SS 15. Select by flow direction (straightway), connection (butt weld EN 10220) and top. EN 10220 and ASME 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.
