🔍 Key Concepts

• Trace the flow path when solenoid "A" shifts the 4/3 directional control valve (which port gets pump pressure and which goes to return). • Determine which cylinder port (cap end C vs rod end D) is being pressurized to figure out whether the piston extends or retracts. • Identify where the flow control valve (with check valve) is located: is it controlling flow into the cylinder (meter‑in) or out of the cylinder (meter‑out) during this solenoid A condition?

💭 Think About

• When solenoid "A" is energized, in which direction does the valve spool move, and which internal passage symbol now connects the pump line to the cylinder ports? • Looking at the symbol in the box at the rod end, during extension or retraction, does fluid pass through the adjustable restriction or through the free‑flow check valve? • For the motion you’ve identified, is the cylinder speed governed by restricted flow or by an unrestricted path back to the reservoir?

✅ Before You Answer

• Verify which port (C or D) is connected to pressure and which to tank/return with solenoid "A" energized. • Confirm whether the flow control + check valve is in the pressure line feeding the moving side of the piston or in the return line from the opposite side. • Check if, in this solenoid position, the cylinder movement path includes the adjustable restriction (controlled rate) or bypasses it (uncontrolled rate).
