Tank Blanketing Valves

Tank blanketing valves are commonly used in tank storage systems to prevent and protect against explosions (avoiding flammable liquids being vented from a vessel), to control product contamination against external air that may fill the vapor space, to reduce evaporation losses (consequently, production losses), to reduce internal corrosion (caused by air and moisture) and to prevent vacuum condition. The blanketing process consists of covering the stored medium, usually a liquid, with a gas (normally N2).
