Danfoss CHV-X 65 function module (also called Top Complete) for the SVL Flexline modular industrial-refrigeration platform, store code 148B5827. 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 65 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 52 bar g (754 psig); media temperature -60 to 150 C (-76 to 302 F). net weight 1.855 kg, gross weight 1.971 kg. Specifications per Danfoss store code 148B5827.
