There are various types of electrohydraulic valves which can be applied in many different ways. Common variations include proportional and on/off versions and in closed-loop or open-loop control.

The previous hydraulic circuit incorporated a proportional directional-control valve, as well as a proportional-relief valve. The relief valve usually controlled the variable-volume pump’s ...
