Abstract
A control valve assembly for a load carrying vehicle that includes a storage space and a dumping mechanism that is movable between an open position that allows access to the storage space and a closed position that inhibits access to the storage space. The control valve assembly includes a housing and a valve that is positioned within the housing and is movable between a first position, wherein the dumping mechanism is moved toward the open position, and a second position, wherein the dumping mechanism is moved toward the closed position. First, second, and third actuation systems are in communication with the valve and are operable to actuate the valve between the first position and the second position.
