How many positions does a spring centered valve have

How many positions does a spring centered valve have

• A. one
• B. three
• C. two
• D. four

Answer: (B)

Spring-centered valves are built with a central, neutral position plus two outer positions. The center is held in place by springs, giving a safe default state when no actuation is applied. When you energize one side, the spool shifts to one outer position to route flow in a specific way; when actuation stops, the springs return the spool to the center. That central position plus the two end positions means there are three distinct positions in total.
