In a 3-position, 5-way DCV, what holds the valve in the mid-position?

Explanation:
In a 3-position, 5-way DCV, the mid-position is typically held by springs. When no actuation force is applied, springs at opposite ends push the spool back to the center, creating a defined neutral or center-off state. This spring-centered configuration ensures the valve reliably returns to center after any command and provides a predictable resting condition. Detents might give a tactile feel for center, but they don’t automatically restore the valve to center like springs do; manual override and pilot pressure are active controls used to move the valve, not the default method that keeps it in mid-position.
