Danfoss SVA-S SS 50 straightway shut-off (stop) valve, 50 mm (2 in) socket weld ASME B 16.11, stainless steel, 52 bar (code 148B7004)

Danfoss SVA-S SS 50 shut-off (stop) valve for the SVL Flexline industrial-refrigeration range, store code 148B7004. Stainless-steel straightway body with socket weld connections both ends to ASME B 16.11. The SVA-S is a hand-operated shut-off (stop) 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; shut-off is bi-directional (bi-flow). Applicable to R717 (ammonia), R744 (CO2), HFC/HCFC refrigerants and oils. Nominal size 50 mm (2 in); flow coefficient Kv 80 m3/h (Cv 92.8 gal/min). Top equipment: Cap. Maximum working pressure 52 bar g (754 psig); media temperature -60 to 150 C (-76 to 302 F). Net weight 4.65 kg, gross weight 5.75 kg. Conformity assessment PED 2014/68/EU, Category II. Specifications per Danfoss store code 148B7004. EAN 5702424600471.

Compatibility

Danfoss SVL Flexline SVA-S SS 50. This code is the straightway SVA-S SS 50 with socket weld (ASME B 16.11) ends and cap top. Socket-weld (ASME B 16.11), EN 10220 and ASME B 36.19M/B 36.10M 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.
