Marine atmospheric corrosion: When exposed to high temperature, high salt, and high humidity marine atmosphere, the exterior of the valve also needs good anti-corrosion measures.

If the air drying system of the factory (such as freeze dryer, desiccant dryer) is inefficient or malfunctions, a large amount of liquid water and water vapor may enter the pneumatic system.

Hygiene level: Do you need to comply with international hygiene standards such as 3-A, FDA, EHEDG, etc? This directly affects surface smoothness, design, and materials.

Meaning: The maximum non impact working pressure that a valve can withstand at a specified temperature (usually ambient temperature, such as 20 ° C).

When the system is shut down or undergoing maintenance, be sure to drain all water or residual media from the valves and pipelines, especially for valves that have not been used for a long time.
