Manual Extract: Relief Valve Pressure Setting

n

Follow these steps to adjust the relief valve pressure setting to ensure optimal performance:

• Remove the hex cap and spring from the top of the circuit relief valve.
• Inspect the plunger for any damaged or worn parts or seals. Repair as necessary.
• Add or remove shims to adjust the pressure setting. Each shim measures 0.254 mm (0.010 in) and alters the pressure by 3.4 to 10.3 bar (50 to 150 psi).
• Reinstall the spring and hex cap on the circuit relief valve.
• Install the circuit relief valve back into the equipment control valve and perform the pressure test according to segment A.12.A.
• Make further adjustments to the valve, if necessary.
• Once the pressure setting is correct, disconnect the hand pump and reconnect the hydraulic line.
