Product Description
Danfoss CHV-X SS 25 check (non-return) 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 spring-loaded check valve permits flow in one direction only and closes on reverse flow to protect compressors, pumps and downstream equipment. 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.

Compatibility & Fitment
Danfoss CHV-X (stainless) check 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. EN 10220 and ASME weld-end variants, and angleway vs straightway, are separate codes and are not interchangeable — confirm the mating pipe standard and flow direction before ordering.
