Product Description
Danfoss SVA-S SS 50 hand-operated shut-off (stop) valve, store code 148B5755, straightway stainless steel body fitted with a hand wheel. 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 plus spindle packing 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 50 mm (2 in), butt weld connections to ASME B 36.19M Schedule 10; flow coefficient Kv 65 m3/h (Cv 75.14 gal/min). Stainless steel housing. Maximum working pressure 52 bar g (754 psig); media temperature -60 to 150 C (-76 to 302 F). net weight 4.628 kg, gross weight 5.291 kg. Conformity assessment PED 2014/68/EU, Category II. Specifications per Danfoss store code 148B5755.

Compatibility & Fitment
Danfoss SVL Flexline SVA-S SS 50. SVA-S is the standard neck. Select by flow direction (straightway), connection (ASME B 36.19M Schedule 10) and top (hand wheel). EN 10220, ASME B 36.10M and ASME B 36.19M 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.
