PV/EB Pressure or Vacuum Relief Valve

Brand: PROTEGO
The atmospheric deflagration and endurance burning proof PV/EB type Protego valve is a highly developed combined pressure/vacuum relief valve for high flow capacities with an integrated flame arrester unit.

It is primarily used as a safety device for flame transmission proof in-and 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 and endurance burning if stabilized burning occurs.

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

The Protego PV/EB valve is available for substances of explosion group IIA (NEC group D MESG > 0.9 mm).
Features
  • Requires only 10% overpressure to full lift
  • Through 10% technology higher set pressures can be used which results in product loss reduction compared to conventional 40% and 100% overpressure technology vents (Compare API 2000)
  • Increased design flexibility through higher reseating pressures; vents reseat when conventional vent is still discharging costly product or nitrogen
  • High performance seal reducing product loss below EPA's 500 ppm rule preventing environmental pollution
  • The valve disc is guided within the housing to protect against harsh weather conditions
  • Can be used as protective system according ATEX in areas subject to explosion hazards
  • FLAMEFILTER provides protection against atmospheric deflagration and endurance burning
  • FLAMEFILTER integrated into the valve saves space and weight
  • FLAMEFILTER protected from clogging through product vapor
  • Protego flame arrester unit has a low pressure drop
  • Flame transmission proof condensate drain
  • Maintenance friendly design
  • Special design with lifting gear can be purchased
