DE/S-IIB3 High Velocity Pressure Relief Valve

Brand: PROTEGO
The deflagration and endurance burning-proof Protego DE/S type device is a state of the art high velocity vent valve working on the principle of a dynamic flame arrester. 

It is primarily used as a safety device for flame transmission proof venting of cargo spaces and loading systems for inland waterway vessels during the loading process and on the journey. 

The valve offers reliable protection against excess pressure, prevents product losses almost up to the set pressure and provides protection against atmospheric deflagrations as well as endurance burning if stabilized burning occurs. 

The Protego DE/S high velocity vent valve is available for substances of explosion group IIB3 (NEC group C MESG ≥0.65 mm).
Features
  • Pressure is set with corrosion resistant permanent magnet
  • Jump characteristic within minimum overpressure to a full lift
  • Excellent tightness for minimum product loss and environmental pollution
  • Set pressure very near to the relieving pressure enables optimum pressure maintenance in the system
  • Can be used as a protective system according to ATEX in areas subject to an explosion hazard
  • Protection against atmospheric deflagrations and endurance burning
  • High flow capacity
  • Maintenance-friendly design
  • Internal parts protected by bellows
  • Manual lift gear to pop valve cone
  • Side connection for a vacuum relief valve
  • Design promotes rain water drainage
  • Prevents gas build up on deck
  • Specially developed for in land water way barges
