Danfoss CHV-X 100 function module (also called Top Complete) for the SVL Flexline modular industrial-refrigeration valve platform, store code 148B5781. The function module is the complete field-serviceable operating top part — top part, one gasket and four bolts — that mounts on the matching CHV-X 100 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 non-return (check) 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 5.878 kg, gross weight 5.909 kg. Specifications per Danfoss store code 148B5781.
