Claim:
A spray rate regulator valve, comprising: a valve body having an inlet port, adapted for connection to a constant flow of liquid spray solution, having a bypass port, adapted for connection to a solution tank, and having a boom port, adapted for connection to a spray boom, a hollow, spherical valve ball mounted in said valve body for rotation about a rotation axis aligned with said inlet port and having a first opening leading to an interior of said ball and being of a circular configuration centrally located on said axis; said valve ball being provided with second and third openings leading to said interior of said ball and being so located relative to said bypass and boom ports that, when said valve ball is in a first extreme position, flow is permitted only between said inlet port and said boom port, when said valve ball is in a second extreme position, flow is permitted only between said inlet port and said bypass port, and when said valve ball is in an intermediate position between said first and second extreme positions, flow is divided between said bypass and boom ports, with the flow from said boom port increasing and the flow from said bypass port decreasing as said valve ball moves toward said first extreme position from said intermediate position, and with the flow from said bypass port increasing and the flow from said boom port decreasing as said valve ball is moved toward said second extreme position.
