804001694 main control valve XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Main Control Valve 804001694 – Intelligent Hydraulic Hub, the Core of Ultimate Performance Control

Product Core Positioning

The XCMG original XE2000 main control valve (part number: 804001694) adopts electro-hydraulic proportional pilot control technology, integrating 32 sets of high-precision valve cores, achieving a flow control accuracy of ±0.8%. It is a core component of the hydraulic system in heavy-duty conditions such as mining and large-scale earthmoving projects. This valve body has passed a 5000-hour extreme durability test, extending its lifespan by 60% compared to the industry standard.
