Patent ID: 8328162

Claim:
A pivotable control valve assembly comprising: a valve unit configured to be coupled to a water treatment device, the valve unit including a valve body and a valve piston configured to move between at least two positions in the valve body to control a flow of fluid through the valve unit and in to and out of the water treatment device; a drive unit including a housing and a drive mechanism located in the housing, the drive mechanism being configured to drive the valve piston, wherein the drive unit includes a user control mounted on at least one side of the housing, the user control being coupled to the drive mechanism to allow a user to control the drive mechanism, positioning of the valve piston, and the flow of fluid in to and out of the water treatment device; and a coupling mechanism pivotably coupling the valve unit to the drive unit, the coupling mechanism including a valve coupling coupled between the drive mechanism in the drive unit and the valve piston in the valve unit, wherein at least the valve coupling is configured to pivot when the drive unit pivots such that the user control is pivoted to a plurality of different user access positions in which the drive unit can actuate the valve unit.
