🔍 Key Concepts

• Meter-in vs meter-out flow control depends on whether the restriction is on the line going into the actuator or the line coming out of it • A bleed-off circuit uses a flow control valve in a branch line back to the tank, so part of the pump flow is diverted before it reaches the directional valve/actuator • Trace the flow from the pump to the cylinder and to the tank, and notice which path contains the adjustable restriction symbol

💭 Think About

• Start at the pump symbol and follow the main pressure line toward the directional valve and cylinder: does the flow control valve lie directly in that line, or is it on a side branch? • Ask yourself whether the adjustable restriction is controlling the flow into the cylinder, the flow leaving the cylinder, or simply diverting some pump flow back to the reservoir • Compare what you see to the typical textbook sketches of meter-in, meter-out, and bleed-off circuits: which one has the flow control in parallel with the load rather than in series with it?

✅ Before You Answer

• Verify which component in the diagram is the flow control valve (look for the variable orifice symbol with an arrow) • Check whether the flow control is in the pressure line to the actuator, the return line from the actuator, or in a branch line to the tank • Confirm whether the cylinder can still receive full line pressure while only part of the pump output is being throttled or bypassed—this is key to distinguishing a bleed-off style circuit from meter-in/meter-out
