A 4/2 DCV offset P to B _______ when de-energized.

• A. Connects P to A
• B. Connects P to T
• C. Connects A to T
• D. All of the above

Answer: (C)

In a 4/2 directional control valve, there are two main port-to-port routes that define the two spool positions: one position connects P to A and B to T, while the other connects P to B and A to T. If the valve is described as offset toward P to B, the rest (de-energized) position is biased to the configuration that connects A to T. So when the system is not energized, A and T are connected, providing a path from the A side back to the tank return. Energizing the valve would shift the route to P to B and A to T, changing which port on the work side receives pressure.
