To convert hydraulic energy into mechanical energy, the hydraulic system needs to control the output hydraulic flow and pressure according to the operational requirements, and the Tractor Hydraulic Valve is one of the key components to control the output flow and pressure of the hydraulic system.

Reasons for the failure of tractor hydraulic valves

The hydraulic valve is used for too long, and the fitting clearance caused by wear, cavitation and other factors is too large, and the internal leakage increases.

The hydraulic oil is not clean, and the hydraulic valve spool is clamped or malfunctioning due to the deposition of pollutants.

mini excavator, backhoe loaders hydraulic valve main maintenance content

1.The valve core and valve body bore of the spool of the spool assembly: when the gap between the two is 20%-25% larger than the assembly gap value specified in the product drawing, the valve core must be repaired after increasing the size.

2.Spool and seat of poppet valve components: When the conical seat seal is in poor contact, the poppet valve can automatically compensate for the gap under the action of the spring, so only grinding is required.

3.Repair of valve components such as jamming, brushing, grooves, etc.

4.Repair of pressure regulating springs.

5.Replacement of seals
