Claim:
A control valve assembly for a load carrying vehicle that includes a storage space and a dumping mechanism 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 comprising: a housing; a valve positioned within the housing and 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; a knob having an indication surface extending about a substantial portion of a periphery of the knob, the knob directly connected to a movable member of the valve and movable between an extended position, wherein the valve is moved to the first position, and a retracted position, wherein the valve is moved to the second position; and a shroud coupled to the housing, wherein the shroud substantially surrounds the indication surface when the knob is in the retracted position to hide the indication surface from view, wherein the indication surface at least partially extends outside of the shroud when the knob is in the extended position; and wherein the shroud includes an access aperture configured to provide access to the knob within the shroud to facilitate a user moving the knob from the retracted position to the extended position.
