Danfoss REG-SB 65 function module (also called Top Complete) for the SVL Flexline modular industrial-refrigeration platform, store code 148B5824. The function module is the complete field-serviceable regulating (throttling) operating top part — supplied as the top part with one gasket and the mounting bolts — that fits the matching REG-SB 65 regulating valve housing. A scaled spindle top gives repeatable manual throttling of liquid, suction, hot-gas and oil flow; the back-seating spindle lets the packing be serviced in operation. Flow area 1978 mm2 (3.065 in2). 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 2.802 kg, gross weight 4.761 kg. Specifications per Danfoss store code 148B5824.
