Product Description
Danfoss SCA-X 50 combined check and stop valve, store code 148B5704, angleway 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 50 mm (2 in), socket weld connections to ASME B 16.11; flow coefficient Kv 45 m3/h (Cv 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. Specifications per Danfoss store code 148B5704. EAN 5702428479035.

Compatibility & Fitment
Danfoss SVL Flexline SCA-X 50. Select by flow direction (angleway), connection (socket weld ASME B 16.11) 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.
