Danfoss CHV-X 125 function module (also called Top Complete) for the SVL Flexline modular industrial-refrigeration platform, store code 148B5782. The function module is the complete field-serviceable non-return (check) operating top part — supplied as the top part with one gasket and the mounting bolts — that fits the matching CHV-X 125 check valve housing. It gives the spring-loaded non-return (check) function that allows flow one way and closes on reverse flow, protecting compressors and pumps against back-flow. It is the repair/replacement assembly, not a complete valve and not a loose gasket, so the function can be renewed without cutting the housing out of the line. For R717 (ammonia), R744 (CO2) and fluorinated refrigerants and their oils. Maximum working pressure 65 bar g (943 psig); media temperature -60 to 150 C (-76 to 302 F). net weight 9.819 kg, gross weight 10.73 kg. Specifications per Danfoss store code 148B5782.
