What component provides the restoring force to return a 3-position, 5-way DCV to center when not actuated?

• A. Springs
• B. Detents
• C. Hydraulic pressure
• D. Manual override

Answer: (A)

Spring-centered design is used to return the valve to its center position when actuation stops. In a 3-position, 5-way DCV, springs are positioned behind the valve spool and continually push it toward the center. When you push or pull the actuator, you compress or extend these springs; oncerelease, the springs force the spool back to center, restoring the default flow paths.

Detents simply give a tactile feel and help hold the spool in a chosen position, but they don’t provide the centering force. Hydraulic pressure could move or hold the spool under certain conditions, but it isn’t the mechanism that automatically returns the valve to center. A manual override is an operator input, not the automatic restoring force.
