ABSTRACT:
A control valve for controlling the flow of fluent material from a machine, the machine having a frame including a hopper and a tube mounted to the hopper, an auger within the tube and a hose mounted to the tube. The control valve has a clamp, which has a first arm mounted to the frame on a first side of the hose and a second arm mounted to the frame on an opposite side of the hose. The first arm is movably mounted to the frame in a direction toward the hose. A prime mover is drivingly linked to the first arm and the frame for displacing the first arm toward the hose, thereby clamping the hose between the first and second arms for restricting the flow of fluent material through the hose.
