The 3-way DCV spool is held in the energized position by the __________.

Explanation:
In a 3-way DCV, the device that actually moves and holds the spool in the energized position is the operator, typically a solenoid. When power is applied, the solenoid creates a magnetic field that shifts the spool and keeps it in the energized state. The spring’s job is to return the spool to the de-energized position when power is removed. A pilot is a separate control path used to move the valve, not the element that maintains the energized condition. A generic mechanism is too vague to describe the actual holding action.
