VD/TS Pressure or Vacuum Relief Valve

Brand: PROTEGO
Request Information
The atmospheric deflagration-proof VD/TS 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. 

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

The Protego VD/TS device is available for substances from explosion groups IIA to IIB3 (NEC group D to C MESG ≥0.65 mm).
Features
  • Requires only 10% overpressure to full lift
  • Extreme tightness and hence least possible product losses and reduced environmental pollution
  • 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)
  • The Valve disc is guided within the housing to protect against harsh weather conditions
  • Can be used as protective system according to ATEX in areas subject to explosion hazards
  • FLAMEFILTER provides protection against atmospheric deflagration
  • FLAMEFILTER integrated into the valve saves space
  • FLAMEFILTER protected from clogging through product vapor
  • Protego flame arrester unit has low pressure drop
  • Optimized flow performance
  • Maintenance friendly design
  • Sturdy housing design
  • Superior technology for API tanks
