Danfoss SCA-X SS 65 angleway check and stop valve, 65 mm (2 1/2 in) butt weld ASME B 36.10M Schedule 40, stainless steel, 52 bar (code 148B7012)

Danfoss SCA-X SS 65 check and stop valve for the SVL Flexline industrial-refrigeration range, store code 148B7012. Stainless-steel angleway body with butt weld connections both ends to ASME B 36.10M Schedule 40. The SCA-X in the Danfoss SVL Flexline range combines a spring-loaded check function with a manual shut-off, so one valve both prevents reverse flow and isolates the line for service in industrial refrigeration plant. Applicable to R717 (ammonia), R744 (CO2), HFC/HCFC refrigerants and oils. Nominal size 65 mm (2 1/2 in); flow coefficient Kv 72 m3/h (Cv 85 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 6 kg, gross weight 6.95 kg. Conformity assessment PED 2014/68/EU, Category II. Specifications per Danfoss store code 148B7012. EAN 5715162477427.

Compatibility

Danfoss SVL Flexline SCA-X SS 65. This code is the angleway SCA-X SS 65 with butt weld (ASME B 36.10M Schedule 40) 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.
