What cylinder action results from shifting the directional control valve to the left flow block?

• A. The cylinder rod retracts
• B. The cylinder rod extends
• C. The cylinder stops moving
• D. The cylinder fills with fluid

Answer: (B)

The cylinder action that occurs when shifting the directional control valve to the left flow block usually results in the extension of the cylinder rod. In a hydraulic or pneumatic system, the directional control valve regulates the flow of fluid or air to and from the cylinder. When the valve is shifted in a manner that directs flow to the extend port of the cylinder, it allows fluid to enter the extension side of the cylinder, pushing the piston and thereby causing the rod to extend. This operation is essential in various applications where controlled movement is required, such as in automation systems, machinery, or robotics. Understanding how the directional control valve interacts with the actuator is crucial for effective design and troubleshooting of fluid power systems.
