Danfoss REG-SA 25-40 function module (also called Top Complete) for the SVL Flexline modular industrial-refrigeration valve platform, store code 148B5763. The function module is the complete field-serviceable operating top part — top part, one gasket and four bolts — that mounts on the matching REG-SA 25-40 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 178 mm2 (0.275 in2). It is the repair/replacement assembly, not a complete valve and not a loose gasket, so the regulating (throttling) 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 1.958 kg, gross weight 2.573 kg. Specifications per Danfoss store code 148B5763.
