WUYI's self-operated nitrogen-sealing control valve consists of a control valve, actuator, pilot controller, and pressure spring. It is designed to maintain constant pressure of the protective gas (typically nitrogen) at the top of a storage vessel, preventing direct contact between the stored material and air. This avoids material evaporation, oxidation, and ensures container safety. It is suitable for gas-sealing protection systems in various large-scale storage tanks.
