GRACO 563157 - Automatic Relief Indicator for Mx Divider Valves, 1000 PSI, 1/4" 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 lubrication is restored, the spring resets the piston, allowing the lube system to keep operating even when a lube point is blocked.

This pressure relief valve is specifically required for use with pressure relief-to-atmosphere kits 571058 and 571070. Part of a series of pressure relief valves with different pressure ratings ranging from 52 bar to 207 bar. Requires separate pressure switch connected to audible or visual alarm for high pressure warning. Green retainer color indicates 1000 psi rating. Document recommends selecting next higher pressure rating when replacing discontinued indicators. 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. Color coded by pressure rating - green indicates 1000 PSI rating.
