🔍 Key Concepts

• Directional control valve vs. pressure control valve in hydraulic systems • Functions of three-position, sequencing, unloading, and counterbalance valves • How flow direction and actuator movement are controlled in hydraulics

💭 Think About

• Ask yourself: Which type of valve is primarily used to start, stop, and change the direction of flow to an actuator (like a cylinder or motor)? • Consider: Which of these valves is most closely associated with controlling the direction of movement (extend/neutral/retract) rather than controlling pressure or sequence? • Think about: Which options are mainly related to pressure control or system protection rather than changing the path of the fluid?

✅ Before You Answer

• Identify which option is typically used to control flow paths to a cylinder or motor (e.g., extend, neutral, retract). • Separate valves that mainly control pressure (such as setting or relieving pressure) from those that control direction of flow. • Verify which valve type is commonly shown as having multiple positions on hydraulic circuit diagrams for actuator control.
