Self-Operated micro-pressure Control Valve

Self-Operated micro-pressure control valve, which used to upstream pressure lower than 1.4Mpa and operate temperature lower than 120 degree, adjust pressure range is 0.14 to 7.2Kpa, the flow non-corrosive gases . Installation and adjust convenient, easy maintenance
Set pressure range 14 to 720mm H2o High sensitivity, high precision

nirogen 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 is mainly used to keep the container at the top of the shielding gas (usually nitrogen) pressure constant, so as to avoid directe contact with the air container material, prevent evaporation materials, oxidation, and the safety of vessel; This series of nitrogen sealing device is especially suitable for the gas seal of the vessel. This series of nitrogen sealing device is especially suitable for the gas seal protection system of all kinds of large storage tanks. It can be divided into two tupes: niteogenrelief type(K type )and nitrogen supply type(B type)
