Part of a series of automatic relief indicators with various pressure ratings from 52 bar to 207 bar When replacing indicators, if original pressure rating is no longer available, select next higher available pressure rating. Separate pressure switch for audible/visual alarm recommended for high pressure warning. This is an automatic relief indicator that pinpoints lube line blockage but allows the lube system to continue supplying lubricant to points that are not blocked. Used primarily in secondary divider valves. The excessive pressure created by line blockage moves a piston, enabling lubricant to escape through a vent. When pressure is relieved the spring resets the piston. A separate pressure switch connected to an audible or visual alarm should be used to warn of high pressure.
