GRACO 563186 - Relief Valve, 1/4 1450 PSI, 1/4"-18 NPTF

Rupture-to-Atmosphere Indicator complete assembly designed to provide visual indication when system pressure has been exceeded. Features a replaceable rupture disc that bursts at predetermined pressure levels to protect centralized lubrication systems from overpressure conditions.

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.
