Several examples of this condition may include:  exposure to fire, chemical reaction or failure of the breather vent to operate.

The protection provided by emergency vents is often required by municipal “Flammable Liquids Codes” to prevent the possibility of tank rupture and subsequent loss of product.

OCECO Type V-108 Vent Valves are corrosion resistant in petroleum as well as hydrocarbon storage applications.  They are stem guided with self closing covers that reseat themselves automatically after tank pressures have been relieved.  As these vents do not remain open longer than necessary, costly evaporation losses are prevented.
