A bow action valve for controlling the flow of material includes a valve body having at least one orifice and a closure plate. The closure plate is secured in front of the valve body at two opposite ends, with one end secured at a substantially fixed location on the valve body, and the other end free to move toward and away from the fixed end. The free end may be moved with a component of motion in the direction of the fixed end to bow the plate means and thereby vary the distance between the plate and the orifice to control the flow of material through the valve body.
