Nitrogen sealing device control valve

Introduction and Application

ME300W02 control valve of nitrogen sealing device is composed of control valve, actuator, pressure spring, commander, pulse tube and so on. It is mainly used to keep the pressure of the protective gas (usually nitrogen) at the top of the container constant, so as to avoid the direct contact between the material in the container and the air, prevent the material from volatilizing, being oxidized, and the safety of the container. It is especially suitable for the gas seal protection system of all kinds of large storage tanks.
