Part of a complete family of automatic relief indicators available in pressure ranges from 52 bar to 207 bar for various equipment series Should be used with a separate pressure switch connected to an audible or visual alarm to warn of high pressure. Formerly identified by spring retainer color (now pressure ratings are stamped on body). Recommended to select next higher pressure rating when replacing discontinued models. Purple colored 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 the 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.
