PV/EBR-E Pressure or Vacuum Relief Valve

Brand: PROTEGO
The deflagration-proof and endurance burning-proof PV/EBR-E type Protego valve is a highly developed combined pressure/vacuum relief valve for high flow capacities with an integrated flame arrester that is specially used for applications handling ethanol.

It is primarily used as a safety device for flame transmission proof outbreathing on tanks, containers and process engineering apparatus.

The valve offers reliable protection against excess pressure and vacuum, prevents the inbreathing of air and product losses almost up to the set pressure and also protects against atmospheric deflagration as well as endurance burning if stabilized burning occurs.

The Protego flame arrester unit is designed to achieve minimum pressure drop with maximum safety.

The Protego PV/EBR-E valve is available for substances of explosion group IIB1 (MESG ≥0.85 mm) and provides specific protection against deflagration and endurance burning of alcohol/air mixtures (Such as ethanol/air).
Features
  • Selecting set pressure close to relieving pressure results in product loss reduction
  • More design flexibility through higher reseating pressures; vents reseat when conventional vent is still discharging
  • The valve disc is guided within the housing to protect against harsh weather conditions
  • High performance seal reducing product loss below EPA's 500 ppm rule preventing environmental pollution
  • Can be used as protective system according to ATEX in areas subject to explosion hazards
  • Safe against deflagration and endurance burning of alcohol/air mixtures from explosion group IIB1
  • High flow capacity through large flame filter cross-section, results in low pressure drop
  • FLAMEFILTER provides protection against atmospheric deflagration and endurance burning
  • FLAMEFILTER integrated into the valve saves space and weight
  • FLAMEFILTER protected from clogging caused by product vapors
  • Flame transmission proof condensate drain
  • Maintenance friendly design
  • Modular design enables individual FLAMEFILTER and valve pallets to be replaced
  • Special design with lifting gear can be purchased
