The hydraulic control valve for a tractor loader typically consists of a spool inside a cylinder. The movement of the spool controls fluid flow. The valve is similar to a directional control valve, but is specifically designed for loaders, diggers, and other heavy equipment.
Gorilla Spares has partnered with the best vendors and suppliers in the business to fulfill your need for hydraulic control valves that meet or exceed OEM specifications and are 100% interchangeable with many different brands.
We thoroughly research, interview, and audit each partner vendor/supplier we select in order to provide you with ruggedly reliable parts that meet or exceed OEM specifications, have been performance tested, feature a one-year performance guarantee, and are in stock and ready for shipping when you need them.
Troubleshooting Tractor Loader Valve Problems
- External leakage: Clean dirt and oil off of the valve exterior and cycle it a few times to determine the leak source. If leaking is coming from the ports, remove the fitting, look for contamination or damage to the spot face sealing surface and, if necessary, replace the sealing washer. If leakage is coming from the spools or from the spring end caps, replace the spool O-ring seals.
- Loader is slow or won’t lift the load: This may mean that the load exceeds the loader’s capacity. Reduce the load. It could also mean that the pressure setting of the relief is incorrect and needs to be adjusted. The pump may not be functioning correctly. Also check linkages on the joystick to ensure that the spools in the valve are being fully shifted.
- Cylinders become “spongy”: This could be a result of air in the cylinders. With an empty bucket, cycle the cylinders several times to full extension and full retraction with the engine near maximum rpm. Also check the reservoir to ensure there is adequate hydraulic oil. Another cause could be cavitation; the oil supply is not adequate to keep up with the cylinder movement when lowering the boom or rolling out a loaded bucket. It may be necessary to run the engine at a higher rpm or install one-way restrictors in the boom base or bucket rod end hydraulic line.
- System runs hot: Check to see if oil is going over the relief valve while the loader is in use.
