This is a component valve required for use with specific pressure relief-to-atmosphere kits, not a standalone product. Part of a family of pressure relief valves with different pressure ratings. Should be used with a separate pressure switch connected to audible or visual alarm to warn of high pressure. When replacing indicators with discontinued pressure ratings, select next higher available pressure rating. Automatic relief indicator 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. 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. Color coded by pressure – blue indicates 750 PSI rating.
