Tietjen 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
