The PC valve typically operates with a control voltage range. For example, it might have a nominal control voltage of [X] volts, with an allowable variation range from [minimum voltage] volts to [maximum voltage] volts. This voltage is used to power the solenoids or other electro - hydraulic components within the valve to achieve proportional control.
The current consumption of the PC valve depends on the type and number of solenoids and other electrical components it contains. Each solenoid might draw a current of around [Y] amperes during operation. The total current consumption is an important factor to consider for the power supply and electrical system design of the excavator.
