Nitrogen solar container check valve

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. WARNING: Products on this website can expose you to chemicals including lead which is known to the state of California to cause cancer, birth defects or reproductive harm. Compressed nitrogen will become extremely cold when it expands, and excess flow may result in damage to gas valve and other components,s bottle to the pressure regulator. The SCV-R® Check Valve is a non-slam Spring-assisted check valve designed for applications requiring "higher cracking pressures" than the DFT Model SCV® check valve. Nitrogen is used in a wide variety of applications including HVAC, Cryogenics, Food Manufacturing, Storage, and Packaging, Medical, and Special Effects.
