A proportional valve is a direct-acting hydraulic control valve positioned between conventional hydraulic valves and electro-hydraulic servo valves. It enables its output to be proportional to the control input, thereby achieving remote control of hydraulic parameters; it can also serve as a signal converter and amplifier in closed-loop control systems.
