1. A system for applying an agricultural product, the system comprising:
a control valve including:
a moveable valve operator configured to translate between a closed position and an open position;
one or more sensors configured to monitor one or more control valve characteristics; and
a valve controller in communication with the one or more sensors, wherein the valve controller includes:
an actuator configured to repeatedly open and close the valve operator with agricultural product delivered to the control valve;
a comparator configured to compare the monitored one or more control valve characteristics to a primed valve characteristic threshold; and
wherein the valve controller is configured to determine the control valve is in one or more of a primed state or an unprimed state based on the comparison of the one or more control valve characteristics to the primed valve characteristic threshold.
