A detented feature is associated with which type of valve behavior?

• A. Three-position detented
• B. Two-position spring return
• C. Proportional control
• D. Manual override

Answer: (A)

Detented features create stable, discrete positions for a valve by using a mechanical detent that holds the spool in place until another action is taken. In a three-position detented valve, there are three stable states—left, center, and right—each held by a detent so you can feel and hear a click as you move into a position, and the valve stays there without needing continuous actuation. This is why the detented behavior is associated with three-position detented designs. The other options don’t rely on detents: a two-position spring-return uses a spring to snap back to a default position, not a held detent; proportional control allows continuous, variable positioning rather than distinct detent steps; manual override is simply a manual means to move the valve, not about discrete locked positions.
