What is the purpose of a 3/2 valve with a detent?

• A. To hold the valve in one of its two positions until an alternate action occurs; provides positive holding.
• B. To automatically switch between positions at a set interval.
• C. To prevent any movement.
• D. To regulate flow rate.

Answer: (A)

A 3/2 valve with a detent is designed to provide positive, stable holding in either of its two positions. Once you actuate the valve to move to a position, the detent catches and keeps it there even after you release the actuator. To change states again, you perform the opposite action to release the latch and move to the other position. This setup ensures the valve stays in the chosen state reliably, resisting unintended movement from touch, pressure, or vibration. It’s not about automatic cycling, it’s not about preventing movement entirely, and it doesn’t regulate flow rate—it's about deliberate, lock-in of the valve state.
