Series 7800 Emergency Pressure Relief Vent

Provides emergency pressure relief capacity, beyond that furnished by the operating conservation vent on the tank. Under normal operating conditions the vent remains closed.  In the event of an emergency (tank involved in a fire) the pallet is lifted by the increased pressure inside the tank.  This relieves pressure and protects the tank from over-pressurization damage.  It then reseals automatically when the tank pressure is reduced.
  • Settings achieved by weight loading.
  • Provides emergency relief in the event of external fire.
  • Leakage rate of less than 1SCFH of air at 90% of set point.
  • Low-leak pallet design.
