Proportional amplifier cards sit between your command signal and your proportional solenoid valve. When your controller sends out an analog input, this card converts that into a controlled current output that drives the solenoid smoothly and repeatably. Without something like this in the circuit, you'd get jerky, inconsistent valve response. The KBCG series from Vickers, now under Danfoss Power Solutions, handles that signal conditioning so your directional or flow control stays precise even under varying load conditions.
