The N2 blanketing valve is designed to maintain constant gas pressure in the vapor space of storage tanks. Itis capable of regulating the desired pressure within specific limits when liquid runs out or when a vacuum occurs due to a temperature decrease. Additionally, it serves to prevent air and humidity from entering the storage vessel, thereby preserving products and safeguarding against fire. The controller also plays a critical role in protecting the tank from explosions by restricting sparks and preventing fluid outflow through evaporation.
