30W02 double-diaphragm micro pressure regulator is composed of the control valve, actuator, pilot, pressure spring and other parts. It is mainly used to maintain constant pressure of the protection gas (generally nitrogen) at the top of the container, so as to prevent materials in the container from contacting the air, avoid volatilization and oxidation of materials and protect the safety of the container. It is especially suitable for gas sealing protection systems of various large-sized storage tanks.
