Product Description
Danfoss REG-SB 15-20 function module (complete top part) for the SVL Flexline industrial-refrigeration range, code 148B5281. The function module is the field-replaceable working assembly (regulating valve function) that mounts onto an already-welded SVL Flexline valve body of the matching 15-20 mm size band, converting the bare housing into a working REG-SB valve. Supplied as a single pack complete with top part, one gasket and four bolts. Maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). Flow area 115 mm2 (0.178 in2). Servicing the module leaves the welded body and the pipeline undisturbed. Order the matching SVL body separately if not already installed.
