De unde se pot achiziţionaSolicitare informaţii

 Used on MH divider valve applications where lube system pressures exceed 2,500 psi.

  • High pressure from blockage causes a disc to rupture
  • Lubricant forces an indicator pin to protrude, indicating the blockage
  • High pressure backs up through the system and trips a switch to shut the system off
  • When fault is corrected, disc must be replaced and pin reset
