800168971 stop valve shaft XCMG XE2000 excavator spare parts

XCMG XE2000 excavator stop valve shaft 800168971 | Original factory fit, precise flow control, wear-resistant and damage-resistant, ensuring fluid system stability

In the hydraulic and fuel fluid systems of the XCMG XE2000 excavator, the shut-off valve is the “core switch” controlling the flow of media. The original XCMG XE2000 shut-off valve shaft (part number 800168971), as a key transmission component of the shut-off valve, directly determines the accuracy and smoothness of valve opening and closing. It stably transmits operating torque, preventing valve jamming and media leakage caused by shaft wear and deformation, thus building a solid “control defense line” for the safe and efficient operation of the entire machine’s fluid system.

800168971 Shut-off Valve Shaft: Three Core Advantages, Compatible with XE2000

Original factory precise fit: The dimensions strictly follow the design standards of the XE2000 gate valve. The shaft diameter accuracy (tolerance ≤ 0.01mm), keyway specifications, and installation length are completely matched with the valve body. It can be directly assembled without grinding or adjustment, avoiding abnormal valve opening and closing gaps and transmission noise caused by fit deviations. It ensures seamless connection with the valve core and operating mechanism and is compatible with the pressure requirements of the whole machine fluid system.
Precise flow control and leak prevention: The mating surfaces of the shaft and valve body are precision ground (surface roughness Ra≤0.2μm), and when paired with original factory seals, they can achieve efficient sealing, with no media leakage under a working pressure of 1.6MPa; at the same time, the shaft transmission accuracy is high, which can accurately control the valve core stroke, ensure that the valve opens and closes in place, avoid media crossflow caused by incomplete on/off switching, and prevent pressure fluctuations in the fluid system.
Wear-resistant and long service life: Made of 40Cr alloy structural steel, it undergoes quenching and tempering treatment and surface nitriding process, achieving a surface hardness of HV800 or higher, improving wear resistance by 60%. It can withstand frictional losses and impact loads caused by high-frequency operation, and is not prone to journal wear, deformation or breakage. Its service life exceeds 12,000 hours (70% longer than ordinary carbon steel shafts), reducing valve maintenance and replacement costs due to shaft failure.

Stable operation under multiple working conditions, with traceable quality.

Whether the XE2000 is operating in high-dust mining operations, heavy-duty infrastructure construction, or humid and rainy outdoor environments, the 800168971 shut-off valve shaft can reliably perform its transmission and control functions. Each shaft has undergone triple testing by the original manufacturer (dimensional accuracy calibration, hardness testing, and sealing performance simulation testing), supports official XCMG traceability, and complies with ISO 9001 standards and engineering machinery fluid control component specifications, ensuring reliable quality and no hidden problems.

Select 800168971, protect XE2000 fluid control.

If you encounter issues such as stuck XE2000 gate valves, media leakage, or need to replace aging gate valve shafts, the original 800168971 part is the best choice. It ensures precise opening and closing of the gate valve and reliable sealing, preventing system downtime due to fluid system malfunctions and facilitating efficient project operations.
