Pressurization control device for electronic equipment enclosures

1. Field of the Invention A pressurization control device () for controlling positive pressurization of an electronic equipment enclosure, such as, for example, a telecommunications equipment enclosure (or ), wherein the device () combines and integrates a number of valves or other control components and functions into a single, common valve body () or manifold providing a single, shared penetration point () into the enclosure (or ), thereby advantageously minimizing the number of penetrations into and potential leakage points from the enclosure (or ). The valves or other control components may be substantially conventional and may include, for example, a cable air tube connection fitting (); a pressure cutoff valve (); a pressure relief valve (); and a static pressure valve or air stem (); an express fitting (); and an on/off valve ().
