Tank regulators BKVi2
(Low Pressure Vent Valve)
Tank blanketing valves are commonly used in tank storage systems to prevent and protect against explosions (by preventing flammable liquids from venting from the vessel), to control product contamination against external air that can fill the vapor space, to reduce evaporation losses (consequently, production losses), to reduce internal corrosion (caused by air and moisture) and to prevent a vacuum condition.
The blanketing process consists of covering the stored medium, usually a liquid, with a gas (usually N2).
