Q

Which of the listed pressure-control valves would be used in a hydraulic system to temporarily divert some, or all of the pump discharge until the additional flow was required?

🔍 Key Concepts

• Function of an unloading valve in hydraulic power units • How a sequence valve operates in a multi‑actuator system • Difference between pressure control that holds a load vs. pressure control that bypasses pump flow

💭 Think About

• Which valve type is specifically associated with sending pump flow back to tank when system demand is low, then allowing full flow when demand increases? • Think about which valve is used to control the order in which actuators move, and whether that really "temporarily diverts pump discharge". • Which valve is typically used to maintain back pressure on a hydraulic cylinder to prevent a load from falling, and does that match the question?

✅ Before You Answer

• Identify which option is primarily used to protect against overload by relieving pressure at a set limit. • Identify which option is designed to maintain a load in position by preventing reverse flow until a set pressure is reached. • Identify which option’s main job is to dump or divert pump output back to reservoir when full flow is not yet needed.
