Danfoss SCA-X SS 25 angleway check and stop valve, 25 mm (1 in) butt weld EN 10220, stainless steel, 52 bar (code 148B5490)

Danfoss SCA-X SS 25 combined check and stop valve for the SVL Flexline industrial-refrigeration range, in stainless steel. Angleway body with 25 mm (1 in) butt weld connections to EN 10220. The valve combines a spring-loaded check (non-return) function with a manual stop (shut-off) function in one body, so a single valve both prevents reverse flow and can positively isolate the line for service. Maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F); Kv 24 m3/h. Stainless steel construction suits R717 (ammonia), R744 (CO2) and HFC systems where a corrosion-resistant body is specified. Fitted with a cap over the stop spindle as supplied.

Compatibility

Danfoss SCA-X (stainless) combined check and stop valve for the SVL Flexline range. Select by nominal size, direction (angleway / straightway) and connection (weld standard). Shares the SCA-X / CHV-X data sheet. Butt weld to EN 10220 and to ASME B36.19M are separate codes and are not interchangeable — confirm the mating pipe standard before ordering.
