Part of a family of rupture indicators with different pressure ratings. Available with optional O-ring seal (563221) and replacement discs available separately. When fault is corrected, the disc must be replaced and the pin reset manually. Part of the Trabon Performance Indicators product line. Rupture Indicators are only used on MH divider valve applications where lube system pressures exceed 2500 psi. High pressure from the lube line blockage causes a disc to rupture. The lubricant then forces an indicator pin to extend, showing the blockage. The high pressure backs up through the system and trips a switch that turns the system off. When the fault is corrected, the disc must be replaced and the pin reset manually.
