Danfoss SCA-X 50 function module (also called Top Complete) for the SVL Flexline modular industrial-refrigeration valve platform, store code 148B5771. The function module is the complete field-serviceable operating top part — top part, one gasket and four bolts — that mounts on the matching SCA-X 50 stop/check valve housing. It gives the combined check (non-return) plus manual shut-off function so the line can be positively closed for service while still protecting against reverse flow. It is the repair/replacement assembly, not a complete valve and not a loose gasket, so the combined non-return (check) plus manual stop 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 2.519 kg, gross weight 3.752 kg. Specifications per Danfoss store code 148B5771.
