ABOVEGROUND
EMERGENCY VENTS
SERVICE STATION
HARDWARE
803 aboveground emergency vents are designed to work in
conjunction with 802 pressure vacuum vents to prevent an
aboveground storage tank from becoming over-pressurized in
the event of a fire or blockage. When the aboveground tank
reaches a determined pressure, the cast iron lid will raise up
to allow the pressure to release. When the pressure releases,
the cast iron cover will lower and reseat. The sturdy cast iron
body and lid, along with the fluorocarbon O-ring, provide a
tight seal when closed. Aboveground tank vents are designed
to open at 8.0 ounces of pressure.
