What is the Vortex® valve and how does it work?
The Vortex® Valve is an automatic pressure relief valve that regulates air with changing altitude and temperature, while keeping water out. Storm Case pressure equalization vents (Vortex® valves) are the result of a unique molded housing and a special “Gortex” gas-permeable micro-porous membrane that can repel liquids and micro-particles while allowing gas (air) molecules to pass right through the membrane. Liquids, dust and dirt particles are repelled while pressure differentials are automatically equalized by the exchange of air through the membrane. The self-regulating Vortex® valve is completely automatic, so there are no push buttons or moving valve parts.
