860114736 YJ320-01000 Pressure Reducing Valve for XCMG Loader – Transmission Hydraulic System Spare Part​

860114736 YJ320-01000 Pressure Reducing Valve — Wheel Loader Drivetrain Hydraulic System

The pressure reducing valve (Part No. 860114736 / Model YJ320-01000) is a critical pressure-control element within the drivetrain hydraulic system of Chinese-brand wheel loaders . Its function is to step down the high-pressure oil from the upstream circuit to a stable, preset downstream pressure — protecting sensitive components such as the torque converter, transmission control valve, and lubrication circuit from pressure spikes, and maintaining the thermal-hydraulic balance of the whole powertrain .

Public sourcing records associate this part with XCMG LW320F torque-converter parts​ . The broader YJ320 valve family​ is widely used across Chinese loader brands: the closely related model YJ320-01000Z​ (with trailing "Z") has been documented on Shantui SL30W loaders​ , and the YJ320-01000 is also listed in hydraulic-component catalogs as a standard pressure-reducing valve for loader transmission circuits, with documented fitment for Liugong 833, SEM 30F/636/638/639, XCMG 300F/320F, Yutong 936H/931A, Shantui L36/L36K, SDLG 933/936/30F and other 3-ton class loaders .

This particular part (860114736 / YJ320-01000) is listed in the XCMG spare parts system with the associated brand mark "Shantui (山推)" — reflecting the cross-brand nature of the YJ-series valve family .
