ABSTRACT:
A valve for connection to the boom of a crop spraying aircraft for emission of chemicals includes a pressure actuated valve member disposed therein in order to provide positive flow of the chemicals when pumped through the valve and positive dripless turnoff when the pressure is removed from the chemicals. Further, the valve is produced in two pivotally connected sections having a gauge disposed thereon for controlling the spray angle of the emitted chemicals and to thereby adjust the swath covered at each pass.
