GRACO 563166 - Valve Relief 1/8 NPT 1500 PSI, 1/8 NPTF

Automatic Relief Indicator that pinpoints lube line blockage while allowing the lube system to continue supplying lubrication 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 the blockage is removed, the spring resets the piston, allowing the lube system to keep operating when a lube point is blocked.

Part of automatic relief indicator family with pressure ratings from 52 bar to 207 bar Separate pressure switch connected to audible or visual alarm should be used to warn of high pressure. If replacing indicators with pressure ratings no longer available, select available indicators with next higher pressure rating. 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 the lubricant to escape through a vent. When pressure is relieved the spring resets the piston. Color provided for service and in selection of replacement indicator. Indicators used to be identified by the color of the spring retainer located in the end of the indicator.
