Abstract: The present invention relates to a flow control system for sprayer nozzles. The control system includes a solenoid coil and a solenoid plunger. The solenoid plunger can slide into an adapter body, substantially perpendicular to the direction of fluid flow. In reducing the fluid flow through the nozzle, the plunger is moved to block an orifice in the path of the fluid flow, within the adapter. The plunger movement is achieved through the energization of the solenoid coil, with signals sent by a controller. The orifice in the adapter is manufactured to a specific size that allows reduced power consumption to shut off or reduce flow through the nozzle. Also, the orifice is sized to provide unrestricted flow when fully open. By means of the controller, control can be provided individually to each nozzle from a plurality of nozzles on a spraying bar.

Abstract: The present invention relates to a sprayer boom lock valve for automating the setup sequence for sprayer operation from the transport position. The lock valve comprises a lever, spring biased toward a valve closing pin, and a cam secured on the secondary boom of the sprayer boom. When the secondary boom is rotated to release wheel locks in the setup sequence, the cam releases the lever which acts on the valve closing pin to close the valve and prevent any further rotation of the secondary boom. The valve is opened again by a linkage which is pulled tight when the sprayer wings are opened, retracting the lever and opening the valve. The hydraulic drive line is then reestablished to complete rotation of the secondary booms.
