It automatically opens or closes to relieve pressure or vacuum inside the tank, typically actuated by an air cylinder mounted on the vent body. The vent helps protect the tank structure from overpressure or collapse during loading, unloading, and transport. Replacement is necessary when the piston seizes, the vent fails to seal, or the air operator becomes unreliable.
