| A solenoid, direct-acting, three-position, spring-centered, directional control valve is used in a hydraulic system to control a linear actuator. Midway through extension, the push button is released, but the actuator continues to extend slowly. Which of the following conditions represents the probable cause? |
| A) A centering spring has broken and jammed the spool movement preventing the spool from recentering. |
| B) One of the two solenoids has sustained an open in its respective coil. |
| C) The pump coupling has been damaged preventing the pump from developing its required operating speed. |
| D) The detent mechanism has failed, preventing the valve from operating. |
