ABSTRACT:
An agricultural spray implement includes a plurality of removable valve/filter
ozzle cartridges. Each removable cartridge has a single housing that retains a magnetized filter, a high speed solenoid valve, and a spray nozzle. In the event the system filter of the spray implement is removed, fine particles which otherwise might clog the solenoid valves are stopped from entering the solenoid valves by the magnetized filters of the valve/filter
ozzle cartridges. Each cartridge has a clean-out purge valve so that its magnetized filter can be unclogged without removal of the magnetized filter from the cartridge housing. A light emitting diode of the cartridge provides a visual indication that the cartridge is dispensing agricultural liquid. The light emitting diode is turned on when the solenoid valve is controlled to be open. In some embodiments, the light emitting diode is not supplied with current until after the solenoid valve has opened and only a smaller holding current is needed to hold the solenoid valve open.
