Humphrey ProControl™ PCD is a rugged proportional valve controller designed to drive proportional valves through PWM or constant current signals. The versatile design allows great flexibility of various drive/control inputs, or manual operation. Valve and interface can be controlled with a host of data acquisitions, such as PLCs, IOTs, or sensor feedback (closed loop) systems. Consider the ProControl PCD, a simple, intuitive proportional valve driver unit, to operate any Humphrey ProControl™ valve, or competitive units of 1 Amp or less.
