Danfoss CHV-X SS 25 angleway check valve, 25 mm (1 in) butt weld ASME B 36.19M Schedule 40, stainless steel, 52 bar (code 148B6481)

Danfoss CHV-X SS 25 check (non-return) valve for the SVL Flexline industrial-refrigeration range, code 148B6481. The CHV-X permits refrigerant flow in one direction only and closes to prevent back-flow toward pumps, compressors and vessels. This SKU is the angleway body in stainless steel with 25 mm (1 in) butt-weld connections to ASME B 36.19M Schedule 40. Flow coefficient Kv 24 m3/h; minimum opening differential pressure 0.04 bar; flow direction marked by an embossed one-way arrow. Maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). For HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) systems. Built on the SVL Flexline modular platform and serviceable with SVL Flexline spare parts.

Compatibility

Danfoss SVL Flexline CHV-X SS check valve. Select by nominal size (25 mm / 1 in), flow body (angleway) and connection standard (ASME B 36.19M Schedule 40 butt weld). EN 10220 and ASME weld-end preparations are not interchangeable — confirm the mating pipe schedule before ordering. Check-only; where an integral hand shut-off is also required, use the SCA-X stop/check valve of the same size. Mount with the embossed arrow in the direction of intended flow.
