Pressure valve technology

Auto pressure equalization valves (GORE-TEX or similar) are critical for waterproof cases. They allow air pressure to equalize between the case interior and exterior when subjected to altitude or temperature changes. Without a pressure valve, the case can become vacuum-sealed (hard to open) or burst seal at altitude. Pressure valves also reduce condensation by allowing humid air to escape before sealing. KeXinMaterials uses GORE-TEX PM100 valves rated for 1.5 psi pressure differential.

Saltwater testing

For marine applications, we test cases in 5% NaCl solution (simulating seawater) for 1,000 hours. Pass criteria: no visible corrosion, no seal degradation, no foam water absorption. This is more demanding than standard IP testing and ensures our marine cases last 5+ years in saltwater service.
