Abstract
A control valve includes a tube housing, a tube within the tube housing, and a clamp within the tube housing. The tube is disposed between a first portion of the tube housing and the clamp, and the clamp is movable between an open position and a closed position. The clamp in the open position is located away from the first portion of the tube housing, and the clamp in the first closed position is located adjacent to the first portion of the tube housing.
