GRACO 563167 - Valve Relief 1/8 NPT 2000 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 the line blockage is removed, the spring resets the piston, allowing the lube system to keep operating.

Part of a family of automatic relief indicators with different pressure ratings for various system requirements Should be used with a separate pressure switch connected to an audible or visual alarm to warn of high pressure. Pressure ratings are now stamped on the body of the indicator. If replacing indicators with discontinued pressure ratings, select the next higher available pressure rating. 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. Excessive pressure created by line blockage moves a piston, enabling lubricant to escape through a vent. When pressure is relieved the spring resets the piston. Color provided for service aid in selection of replacement indicator. Indicators used to be identified by the color of the spring retainer located in the end of the indicator.
