The return line valve ensures that oil flows in one direction only — toward the reservoir. It prevents backflow that would cause uncontrolled cylinder movement.

A faulty valve is recognized by oil heating up, the boom lowering without a command, and a loss of system power.

Features and application

• Directs oil flow to the reservoir
• Prevents unwanted backflow
• Affects oil temperature in the system
• Replace when the boom lowers without a command
