A control system for digitally monitoring and/or controlling pressure to a pneumatic load such as a stop/suckback valve. Pressure is sensed in the pneumatic fluid input lines to the pneumatic load, and a closed loop control is used to maintain the pressure at a predetermined level. In an alternative

A control system for digitally monitoring and/or controlling pressure to a pneumatic load such as a stop/suckback valve. Pressure is sensed in the pneumatic fluid input lines to the pneumatic load, and a closed loop control is used to maintain the pressure at a predetermined level. In an alternative embodiment, the control system is used to ensure equal dispensing in multi-point dispense apparatus. Thus, pressure is sensed downstream of each valve in fluid communication with a respective nozzle. Any pressure differential detected is corrected by appropriate valve adjustment.
