What does the term 'center' in a hydraulic valve refer to?

Explanation:
Center is the valve’s neutral, resting position when no control input is applied. In this position the valve isn’t directing flow to either side of the actuator, so the actuator doesn’t move. Different valve designs may connect pressure to tank to relieve pressure or block all ports in center, but the common idea is that center equals neutral—the valve sits there when it’s not being commanded. That’s why neutral is the best answer.
