Abstract
A contact tray has a tray deck for receiving a liquid stream and a plurality of valves distributed across the tray deck through which vapor ascends for interacting with the liquid stream. Each valve includes an opening in the tray deck, wall segments that extend upwardly along opposite sides of the opening, and a valve body. The valve body has a trapezoidal valve cover positioned in covering relationship above and extending outwardly beyond the opening and legs that are attached to the valve cover at recesses located at opposite ends of the valve cover. A vent is positioned in one of the legs.
