In a tandem center valve, pressure port P is directed to port T. Which option matches this statement?

• A. P --> T
• B. P --> A
• C. P --> B
• D. P --> C

Answer: (A)

In a tandem center valve, the neutral or center position provides a direct path from the pressure port to the tank port. This means the high-pressure supply is shunted back to the reservoir instead of feeding the actuator ports, keeping the actuators from moving when no command is given. Therefore, the statement that pressure port P is directed to port T correctly describes the center position of a tandem center valve. The work ports A and B stay de-pressurized in this neutral state, preventing unintended actuation.
