Electronically controlled valve system for distributing particulate material

An agricultural application implement comprising:

• a frame;
• a plurality of wheels supporting the frame;
• a fan configured to produce an airflow;
• a plenum connected to the fan;
• a plurality of supply lines connected to the plenum, each supply line of the plurality of supply lines being configured to receive the airflow via the plenum and entrain particulate material in the airflow;
• a plurality of boom sections supported by the frame, each boom section of the plurality of boom sections supporting a plurality of nozzles, the plurality of nozzles of each boom section of the plurality of boom sections being connected to a respective supply line of the plurality of supply lines to distribute the particulate material entrained in the airflow of the respective supply line;
• a plurality of electronically controlled valves, each supply line of the plurality of supply lines being associated with a respective valve of the plurality of electronically controlled valves, each valve of the plurality of electronically controlled valves being actuatable between an open position and a closed position, wherein the airflow in each supply line of the plurality of supply lines is greater when the respective valve of the plurality of electronically controlled valves is in the open position than when the respective valve of the plurality of electronically controlled valves is in the closed position;
• a plurality of pressure sensors, each pressure sensor of the plurality of pressure sensors being configured to generate back pressure data providing a back pressure in a corresponding supply line of the plurality of supply lines;
• and
• a control system in communication with the plurality of electronically controlled valves and the plurality of pressure sensors, wherein the control system executes a program stored in a non-transient medium to:
• receive the back pressure data generated by the plurality of pressure sensors, the data providing the back pressure in each of the plurality of supply lines;
• and
• selectively control each valve of the plurality of electronically controlled valves based at least in part on the back pressure in each of the plurality of supply lines.
