GRACO 563163 - Valve Relief 1/8 NPT 750 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 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.

Part of a series of automatic relief indicators with different pressure ratings from 52 bar to 207 bar. Also available with O-Ring seal versions (563170-563176). Requires separate pressure switch connected to audible or visual alarm for high pressure warning. Blue retainer indicates 750 psi pressure rating. If replacing indicators no longer available, select next higher pressure rating. 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. Blue color coded for identification by color of the spring retainer located in the end of the indicator.
