Tietjen Relief Valve E-VENT

Relief valve E-VENT

In a dust explosion in the interior of containers and equipment the Tietjen relief valve E-VENT rapidly openings for the air outlet and reliable prevents build up of high pressures in the system.

E-VENT - the economic solution for explosion protection:

  • opens when overpressure is in the System
  • vents internal atmosphere and prevents flame outlet
  • provided relief at very slight overpressure Levels
  • rapid depressurization by spring-loaded and frictionless guided valve plate
  • very short closing time
  • secondary flame suppression by closure of the internal atmosphere
  • low profile
  • ATEX certified valve
  • many sizes available
Technical details
  • Pressure reduction, Pred: > 0.05 bar
  • Kst max. permitted: up to 300 bar x m/s
  • Ambient temperature: 0 ... 40 ° C
