WEISHUO's Waterproof and Dustproof Hard Box with Pressure Balance Valve not only achieves an IP67 protection rating but also features a core advantage: an integrated professional waterproof pressure balance valve. This seemingly compact device, when closed, prevents liquid water, water vapor, salt spray, oil contamination, and even bacteria or viruses from penetrating. This means that when the box is air-shipped from low-altitude to high-altitude regions, or experiences significant day-night temperature fluctuations, the pressure inside and outside the box can be balanced by opening the vent valve. The lid remains easy to open while maintaining a dry interior environment.
WEISHUO's Fully Airtight Dustproof and Waterproof Hard Box takes this further. Beyond the pressure equalization valve, it comprehensively optimizes all potential leakage points—including seal groove depth and width, pressure distribution of latches, and hinge sealing treatments. This box can even operate for extended periods several meters underwater or function in vacuum environments, shielding internal equipment from negative pressure effects.
These specialized enclosures find extensive application in deep-sea exploration equipment, high-precision optical instruments, satellite ground testing apparatus, and similar fields.
