Danfoss SCA-X SS 40 angleway check and stop valve, cap, 40 mm (1 1/2 in) butt weld EN 10220, stainless steel, 52 bar (code 148B5664)

Danfoss SCA-X SS 40 combined check and stop valve, store code 148B5664, angleway stainless steel body, fitted with a cap. 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) and fluorinated refrigerants and their oils. Nominal size 40 mm (1 1/2 in), butt weld connections to EN 10220; flow coefficient Kv 30 m3/h (Cv 34.8 gal/min). Stainless 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. Specifications per Danfoss store code 148B5664. EAN 5702428842907.

Compatibility

Danfoss SVL Flexline SCA-X SS 40. Select by flow direction (angleway), 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.
