Sanitary tank blanketing regulators BKV2

(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 from external air that may fill the vapour space, to reduce evaporation losses (hence production losses), to reduce internal corrosion (caused by air and moisture) and to prevent a vacuum condition. 

The blanketing process consists of blanketing the stored medium, usually a liquid, with a gas (usually N2).
