It serves as the primary access point for tank cleaning and inspection while protecting the tank from over-pressurization and vacuum during loading, unloading, and rollover events. The unit includes a built-in 10-inch surge suppression relief valve and a normal vent to handle pressure changes during transit. You would typically replace this if the lid, hinge, or gasket is damaged, if the relief valve fails a pressure test, or if corrosion has compromised the seal.
