GRACO 563188 - Relief Valve, 1/4 2350 PSI, Aluminum, 1/4"-18 NPTF

Complete rupture-to-atmosphere indicator assembly designed to provide visual warning when high system pressure line has occurred. Features a spud assembly with female thread for returning vented lubricant oil to reservoir via tube connection. Includes high pressure switch and/or cycle switch capability for audible or visual warning alarms.

Trabon Performance Indicators are pressure-sensitive devices that pinpoint excessive pressure in Trabon series progressive lubricating systems. These devices, which are installed in the alternate outlet ports of divider valves, signal a fault either by causing an indicator pin to protrude or by releasing lubricant to the atmosphere. All Performance Indicators respond quickly to protect the lube system and locate lube line blockage.

Rupture-to-Atmosphere Indicators for use with MX Divider Valves. A spud assembly is available to return vented lubricant to the reservoir by way of a tube.

• Used in conjunction with system pressure switch–can warn of a fault while allowing lube system to continue to deliver to critical bearings.
• Requires replacement of the rupture disc to restart the lube system.
• Easy information on blocked lines, high system pressure or blocked bearings.

Part of the rupture-to-atmosphere indicator family with spud assembly, specifically designed for 1/4"-18 NPTF connections Part of GRACO's comprehensive centralized lubrication system product line. All pressures have a tolerance of ±500 PSI. Replacement discs are available individually or in packaged quantities. This is a complete assembly that includes a Spud Assembly to return vented lubricant to the reservoir by way of a tube. A high pressure switch provides an audible or visual warning alarm that height system pressure has occurred. Standard on all GRACO pumps - ruptures when pressure reaches predetermined setting, venting lubricant into atmosphere and relieving pressure.
