Series 52600 Emergency Pressure/Vacuum Relief Vent

Brand: Protectoseal Company
Request Information
Protectoseal’s Series 52600 Emergency Pressure / Vacuum Relief Vents are designed to provide emergency relief capacity beyond that available through the operating vents on tanks.

In emergency situations (external fire involvement of the tank), normal venting devices may be too small to prevent over pressurization of the tank.

The Series 52600 provides the necessary pressure relief capacity to maintain the tank in a safe operating range.

The integral vacuum vent provides additional protection against tank collapse due to excessive vacuum in the vapor space.
Features
  • Sizes 16" (DN 400) through 24" (DN 600)
  • Provides emergency relief in the event of an external fire
  • Vents directly to atmosphere
  • Pressure setting achieved by weight loading
  • Vacuum setting achieved by spring loading
  • Leakage rate of less than 1 SCFH of air at 90% of set point
  • Reseats automatically when tank pressure is reduced
  • Conforms to the latest ATEX Directive
  • Patented, FEP film “Air-Cushioned Seating”
  • Low-leak pallet design - certified test reports
  • Available in Carbon Steel, Aluminum & Stainless Steel
