Variable and proportional pilot valves exist, although they are rarer than directional control (DCV) and on/off check valves. These variable valves adjust the output flow rate as the control pressure changes. This mimics the operation of an electrical analog valve, usually working with 0-10 volts or 4-20 mA. It is far … See more Many industries place a lot of emphasis on safety around electrical systems.
