Tank vents (AKA conservation vents, breather vents or pressure/vacuum relief valves) prevent tanks from exploding due to overpressure. They also prevent tanks from collapsing, or imploding, due to vacuum.
The vents relieve overpressure related to pumping fluids into the tank, atmospheric heating of the tank and heating of the tank due to fire that is external to the tank. They also relieve vacuum related to pumping fluids out of the tank and atmospheric cooling of the tank. The customer chooses the point at which the vents provide relief of either pressure or vacuum.
BS&B markets its tank vents under the TankSaf brand name.
