This pressure relief valve is required for use with pressure relief-to-atmosphere kits 571058 and 571070. Part of a family of pressure relief valves with different pressure ratings ranging from 52 bar (750 PSI) to 207 bar (3000 PSI). Separate pressure switch connected to audible or visual alarm should be used to warn of high pressure. Part of the automatic relief indicator family with color-coded spring retainers for pressure identification. 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. When blockage occurs, excessive pressure created moves a piston, enabling lubricant to escape through a vent. When pressure is relieved the spring resets the piston. Color coded by pressure rating – identified by the color of the spring retainer located in the end of the indicator.
