A purge valve is a critical component in protective cases used for shipping and packaging, designed to regulate air pressure inside the case while preventing the entry of dust and water. This valve facilitates the free flow of air in and out of the case, which is essential for maintaining internal and external pressure equilibrium, especially during changes in altitude or environmental conditions.

Functionality:

Pressure Mitigation: The primary function of a purge valve is to equalize the pressure inside the case with the external atmosphere. This is crucial when transporting items from areas at different altitudes, as significant pressure differences can cause physical damage to both the case and its contents.

Protection from Elements: While allowing air to flow, the valve effectively blocks dust and water, safeguarding the contents against environmental damage and contamination.

Types of Purge Valves:

Automatic Purge Valves: These are standard in high-quality cases, such as those offered by brands like Pelican. They automatically adjust the air flow and pressure without human intervention, providing superior protection and convenience.

Manual Purge Valves: These require manual operation to equalize pressure and are typically found in less expensive cases. Manual valves demand attention to prevent potential damage due to delayed pressure adjustment during transit.

Applications:

Purge valves are indispensable in the design of watertight and airtight protective cases used for transporting sensitive equipment such as cameras, scientific instruments, military equipment, and other valuable or delicate products.
