D-SVL-EB-200-IIA Pressure Relief Valve

Brand: PROTEGO
The deflagration-proof and endurance burning-proof D-SVL-EB type Protego valve is a highly developed pressure relief valve for large flows with an integrated flame arrester Protego EB. 

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 prevents product losses almost up to the set pressure; it 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. 

Protego D-SVL-EB valves are available for substances 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)
  • More design flexibility through higher reseating pressures; vents reseat when conventional vent is still discharging
  • 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 in areas subject to explosion hazards
  • Protego flame arrester unit provides protection against atmospheric deflagration and endurance burning
  • Flame arrester unit integrated into the valve saves space, weight and reduces cost
  • Flame arrester unit protected from clogging through product vapor
  • Flame arrester unit has a low pressure drop
  • Flame transmission proof condensate drain
  • Maintenance friendly design
  • Modular design enables individual FLAMEFILTER
