BKVi2
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).

RP45TW
The ADCA RP45TW series pressure reducing station consists of two standard RP45 valves installed in parallel. This system is particularly recommended for installations where a single valve cannot reach the maximum required flow rate or when the consumption variation is significant, being prudent to install two smaller valves instead of a single one in order to avoid oversizing. This system is also recommended when it is vital that the steam supply is not interrupted.
