Emergency vent (pressure relief only) used on aboveground storage tanks, as a code requirement that helps prevent the tanks from becoming over-pressurized and rupturing if exposed to fire. The 244 emergency vent consists of a body and a black powder coated cover that moves up and down on a center pin. Pressure inside the tank forces the cover to lift up off the vent seat, allowing air to exhaust. The center pin guides the movement. When the pressure falls the cover lowers back down onto seat and the vent is automatically reset.
