Danfoss SCA-X 15 angleway stop/check valve, 15 mm (1/2 in) butt weld EN 10220, 52 bar, steel (code 148B5208)

Danfoss SCA-X 15 combined stop and check valve for the SVL Flexline industrial-refrigeration range, code 148B5208. The SCA-X performs two functions in one body: it acts as a check (non-return) valve to prevent reverse flow, and as a hand stop valve that can be closed to isolate the line for service. This SKU is the angleway body in 15 mm (1/2 in) butt-weld connections to EN 10220. Flow coefficient Kv 8 m3/h (Cv 9.3 gal/min); minimum opening (cracking) pressure 0.04 bar (0.62 psi). Steel housing rated 52 bar (754 psig) maximum working pressure, media temperature -60 to 150 C (-76 to 302 F). An embossed one-way flow arrow on the body marks the permitted flow direction. Suits HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) systems. Built on the SVL Flexline modular platform — the complete top part is interchangeable across the SVA-S/SVA-L, REG-SA/REG-SB and FIA functions.

Compatibility

Danfoss SVL Flexline SCA-X stop/check valve. Select by nominal size (15 mm / 1/2 in), body direction (angleway) and connection standard (EN 10220 butt weld). Install with the embossed arrow in the intended flow direction. EN 10220 (DIN) and ASME B 36.10M weld-end preparations are not interchangeable — confirm the mating pipe schedule. Shares the SVL Flexline platform with SVA-S/SVA-L shut-off, REG-SA/REG-SB regulating and FIA strainer functions; the complete top part is interchangeable.
