ARV RELIEF VALVE (3600 PSI) SUITABLE FOR JCB 3CX, 4CX - 25/222499

Technical Specification and Compatibility

A high-quality Anti-Relief Valve (ARV), which screws into the backhoe valve block. Its function is to protect individual sections of the hydraulic system from sudden pressure spikes, which can occur, for example, when the bucket hits an obstacle. The valve releases excess pressure to the tank, protecting the rams, hoses, and the valve block itself from damage.

Part number: 25/222499
Alternative part numbers: 333/C8656, 25/610400
Pressure Setting (PSI): 3600
Application: Backhoe hydraulic valve block

Aftermarket quality product – an intelligent choice combining excellent quality with an attractive price.

The list above is for reference. Before purchasing, we recommend checking the part number on the old component or in the parts catalogue for your machine.

⚠️ Safety Warning

Before replacing the valve, you must completely depressurize the hydraulic system by lowering all attachments to the ground and operating all levers with the engine off. High-pressure hydraulic oil can cause serious injury. Use safety glasses and gloves.

Service Recommendation: Ensure Maximum Lifespan

Replacing the valve is a perfect opportunity to check the condition of the hydraulic oil and filter. Contaminated oil is the most common cause of valve failure. Use high-quality HYPTRON hydraulic oil and change filters to proven REDX brand replacements to ensure the long and trouble-free operation of the entire system.

Part's Role in the Machine and Failure Diagnostics

A relief valve is a "fuse" for a specific hydraulic section. Its failure can manifest in two ways: if it is stuck open, the ram will have no power. If it is stuck closed, it fails to protect the system from overload, risking a burst hose or a damaged ram.

  • › Lack of power on one of the arm functions (e.g., lift, bucket curl).
  • › The arm "drifting down" on a specific function after stopping it.
  • › Very slow operation of one function while others work normally.
  • › Visible oil leaks from the valve itself.

Peace of Mind Guarantee: Why Choose Our Offer?

A faulty valve risks damage to the ram or valve block.

The cost of replacing a valve is negligible compared to the overhaul of a hydraulic ram. Protect your machine from a major failure – order a new GX-AFTER valve and restore full safety and efficiency to your hydraulic system.

🔧 Expert's Guide: Key Installation Tips

  1. Maintain cleanliness: Before unscrewing the old valve, thoroughly clean the area on the valve block to prevent dirt from entering the system.
  2. Replace seals: Always install a new valve with a new set of o-rings and seals.
  3. Use correct torque: Tighten the valve with a torque wrench according to the values in the service manual to ensure a proper seal without damaging the threads.
  4. Check operation: After replacement, carefully start the machine and test the specific hydraulic function, checking its power and smoothness.

Frequently Asked Questions (FAQ)

1. One function on my backhoe arm is weak. Is it definitely this valve's fault?

This is one of the most common causes. If the valve is stuck open or its spring is weak, it will release pressure before the ram reaches full power. Other causes include internal leaks in the ram or wear in the valve block section itself.

2. Can I adjust the pressure on this valve myself?

These valves are factory-set to a specific pressure (in this case, 3600 PSI) and sealed. Attempting to adjust them without proper pressure gauges and knowledge is not recommended and is dangerous. Incorrect settings can lead to damage to the hydraulic system.

3. What is the difference between an MRV and an ARV?

The Main Relief Valve (MRV) protects the entire hydraulic system by setting the maximum pressure for the pump. Anti-Relief Valves (ARVs) are installed on individual sections of the valve block and protect specific rams, often having different pressure settings than the main valve.
