Automatic Relief Indicator
Automatic Relief Indicators pinpoint lube line blockage but allow the lube system to continue to supply lubrication to points that are not blocked. They are used primarily in secondary divider valves. When needed, pressure is relieved through a vent. When pressure is relieved the spring resets the piston. Because these indicators permit the lube sys- tem to continue operating when a lube point is blocked, a separate pressure switch connected to an audible or visual alarm should be used to warn of high pressure.

Rupture Indicator - MH Divider Valves Only
Rupture Indicators are only used on MH divider valve applications where lube system pressures exceed 2500 psi. The high pressure from a lube line blockage causes a disc to rupture. The lubricant then forces an indicator pin to protrude, locating the blockage. The high pressure backs up through the system and trips a switch to shut the system off. When the fault is corrected, the disc must be replaced the pin reset manually.
