In a tandem center valve configuration, the signal from pressure port P is directed to which port?

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

Answer: (A)

In a tandem center valve, the center (neutral) position provides a direct path from the pressure port to the tank port. This means the signal from pressure P is directed to tank T, relieving pressure and keeping the actuator from moving when no command is being issued. To move the actuator, the valve redirects pressure from P to one of the work ports (A or B) while routing the other work port to T, so pressure is applied to one side of the actuator and the other side is drained. So the best answer is P connected to T.
