The pressurization valve found in all watertight cases plays a key role in ensuring its watertightness and facilitating opening after pressure variations. To understand the importance of this component, it is necessary to analyze the concept of atmospheric pressure and its impact on the design of a watertight technical case.

How atmospheric pressure works
Atmospheric pressure can be defined as the force/weight exerted by the column of air on a surface. This value varies depending on altitude, temperature and latitude. Normal atmospheric pressure, equal to 1 atmosphere (1 Atm), corresponds to approximately 1,013.25 Pascal (Pa) and is measured at sea level, at a temperature of 15°C and on a surface of 1 cm2. To measure atmospheric pressure, a barometer is commonly used.

Due to the compressibility of air, the decrease in atmospheric pressure is not linear as in liquids. With increasing altitude, the pressure decreases non-linearly.

Without a pressure regulating system
This concept is crucial in the design of a watertight technical case. In fact, a plastic water bottle, hermetically sealed at an altitude of 3.000 meters, would be crushed once brought down to sea level. Similarly, a watertight case without a pressurization valve would be extremely difficult or impossible to open after an air flight.

The automatic pressure release valve
The valve’s job is to compensate for pressure changes that may occur during transport, for example, when boarding the watertight case on a flight.

Technical cases in the Explorer range are equipped with state-of-the-art automatic valves. These valves have a special internal membrane that allows the passage of air while preventing the flow of liquids in either direction. Due to this feature, the valve adjust the internal pressure according to the external pressure without compromising the watertightness of the product.

Explorer guarantees you maximum protection
In conclusion, the presence of the automatic valve in cases is essential to handle the pressure variations that occur during a trip.

This component allows the case to be easily opened even after an airplane flight, or during a mountain hike, avoiding inconveniences resulting from pressure variations. In fact, thanks to the latest generation of automatic valves found throughout the Explorer range of watertight cases, you can benefit from maximum protection, reliability and ease of use without ever compromising the safety of the contents.
