🔍 Key Concepts

• Location of the flow control valve in relation to the actuator (cylinder) and the pump return line • Difference between metered-in vs metered-out flow control in hydraulic circuits • How bleed-off style circuits route some flow directly back to the reservoir instead of through the actuator

💭 Think About

• Look at whether the adjustable flow control is placed on the line supplying oil to the cylinder or on the line where oil leaves the cylinder and returns toward the control valve/tank • Ask yourself: is the valve throttling the fluid going into the cylinder chamber under pressure, or the fluid leaving the opposite side of the cylinder? • Check if any branch line is taking part of the pump flow and dumping it to tank without passing through the actuator—would that match a bleed-type circuit?

✅ Before You Answer

• Identify the exact line where the needle/flow control symbol is drawn: is it on the pressure feed to the cylinder or on the exhaust/return side? • Confirm whether all pump flow to the actuator passes through the control valve, or if some is diverted directly to tank (which would indicate a bleed-off arrangement). • Verify that the check valve symbol next to the flow control shows free flow in one direction and restricted flow in the other, which is typical for metered-in or metered-out circuits.
