Abstract
A reduced stroke gate valve is provided. The reduced stroke gate valve provides a predetermined or desired flow area for a given bore size through the gate valve while reducing a total length through which the gate valve strokes between an open position and a closed position. The reduced stroke gate valve includes one or more openings that span a non-circular or non-round area within the gate. The non-circular or non-round shape or distribution of opening(s) in the gate may provide a flow area equivalent to a predetermined flow area for a single circular hole that would otherwise be used for the gate valve application, but with a shape or distribution of opening(s) that provides a reduced stroke length to move the gate valve from the open position to the closed position.
