Danfoss SVA-S 40 straightway shut-off valve, cap, 40 mm (1 1/2 in) butt weld ASME B 36.10M Schedule 80, steel, 52 bar (code 148B5631)

Danfoss SVA-S 40 hand-operated shut-off (stop) valve, store code 148B5631, straightway steel body fitted with a cap. The SVA-S is a shut-off valve in the Danfoss SVL Flexline range for industrial refrigeration, used to isolate liquid, suction, hot-gas and oil lines. The globe-pattern body uses a back-seating spindle so the packing can be serviced while the plant stays in operation, and the seal cap gives double sealing to atmosphere; shut-off is bi-directional (bi-flow). Applicable to R717 (ammonia), R744 (CO2) and fluorinated refrigerants and their oils. Nominal size 40 mm (1 1/2 in), butt weld connections to ASME B 36.10M Schedule 80; flow coefficient Kv 31.6 m3/h (Cv 36.53 gal/min). Steel housing. Maximum working pressure 52 bar g (754 psig); media temperature -60 to 150 C (-76 to 302 F). Conformity assessment PED 2014/68/EU, Category II (DN 40). Specifications per Danfoss store code 148B5631.

Compatibility

Danfoss SVL Flexline SVA-S 40. SVA-S is the standard neck; SVA-L is the long-neck version. Select by flow direction (straightway), connection (ASME B 36.10M Schedule 80) and top (cap). EN 10220 and ASME weld-end preparations are not interchangeable — confirm the mating pipe schedule before ordering. 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.
