Abstract
A swing valve includes a body having an inner surface defining an opening, a plate positioned substantially within the opening of the body, and a pivot rod coupled to the body and the plate. The pivot rod defines a pivot axis. The plate is pivotable about the pivot axis relative to the body between an open position and a closed position. The swing valve also includes a locking mechanism coupled to the plate. The locking mechanism includes a member that is movable relative to the plate between a first position, in which the locking mechanism engages the body to lock the plate in the closed position, and a second position, in which the locking mechanism disengages the body to allow movement of the plate relative to the body.
