Nitrogen seal control valve has two kinds of Nitrogen supply regulation and nitrogen release regulation, which can depend on the pressure change of the regulated medium itself to achieve the purpose of automatic regulation and stable pressure. It is mainly used to keep the container at the top of the shielding gas (usually nitrogen) pressure constant, so as to avoid direct contact with the air container material, prevent evaporation materials, oxidation, and the safety of the vessel.
