Self operated nitrogen sealing valve

البند المنتج：ALKV1078

وصف

Product Features

1、Composed of control valves, actuators, pressure springs, controllers, pulse tubes, and other components.

2、Mainly used to maintain a constant pressure of the protective gas (usually nitrogen) at the top of the container, in order to avoid direct contact between the materials inside the container and air, and to prevent material volatilization and oxidation.

3、Gas seal protection system suitable for various large storage tanks. This product has the characteristics of energy saving, sensitive action, reliable operation, and convenient operation and maintenance.
