2. Replace worn-out parts with the corresponding part numbers mentioned in the manual.

Troubleshooting

If experiencing issues with valve operation:

• Check for clogs in the orifices.
• Ensure proper electrical connection if using coils.
• Inspect for any damaged O-rings and replace if necessary.

Frequently Asked Questions

• Q: How do I determine the correct orifice size for my application?
  • A: Refer to the Orifice Diameter table in the manual and select the size based on the flow requirements.
• Q: What should I do if the valve is leaking?
  • A: Check for loose fittings and O-rings. Tighten fittings and replace O-rings if needed.
• Q: Can I use coils with different voltage ratings?
  • A: No, always match the coil voltage with the specified ratings to ensure proper functionality of the valve.

Type “F” flying lead coils must be powered by DC electrical signal. Type P12L coils must be powered by 110 – 120, 50 – 60 Hz AC rectified to DC signal. DIN rectified connectors ( “11” or “12” in model code) can be used to convert AC volts to DC voltage to power the valve.

Orifice Changing Procedure

WARNING

1. Before breaking a circuit connection make certain that power is off and system pressure has been released. Lower all vertical cylinders, discharge accumulators and block any load whose movement could generate pressure. Plug all removed units and cap all lines to prevent entry of dirt into the system.
2. Using a 5/32“ hex key, remove manual actuator plug and spring from the end of solenoid (Tightening torque 6.2 –7.3 N.m 55–65 lbf.in.)
3. Insert extraction tool (878495) into solenoid via the manual actuator opening. Rotate tool until aligned and push pin into slot in armature.
4. Using 1/2“ wrench and tool to prevent the armature from rotating, insert 3/32“ hex key down the center of tool and remove orifice plug.
5. Replace by the same method, tightening orifice snug to ensure the bottoming of threads. Smaller orifices increase response times, larger orifices decrease response time.
