Danfoss REG-SB SS 32 straightway hand-operated regulating valve, 32 mm (1 1/4 in) butt weld EN 10220, stainless steel, 52 bar (code 148B5592)

Danfoss REG-SB SS 32 hand-operated regulating (throttling) valve, store code 148B5592, straightway stainless steel body. The REG-SA (small flow area) and REG-SB (large flow area) are precision regulating valves in the SVL Flexline range used to set liquid, suction, hot-gas and oil flow in industrial refrigeration; a scaled spindle gives repeatable manual throttling and the back-seating spindle allows the packing to be serviced in operation. Nominal size 32 mm (1 1/4 in), butt weld connections to EN 10220; flow coefficient Kv 20 m3/h (Cv 23.12 gal/min). Stainless steel housing. Maximum working pressure 52 bar g (754 psig); media temperature -60 to 150 C (-76 to 302 F). Conformity assessment PED 2014/68/EU, Category II (DN 32). Applicable to R717 (ammonia), R744 (CO2) and fluorinated refrigerants and oils. Specifications per Danfoss store code 148B5592.
