XCMG XE2000 Excavator Pressure Relief Valve 860170901: A Safety Barrier for the Hydraulic System

In the hydraulic system of the XCMG XE2000 large excavator, the pressure relief valve (part number: 860170901) is a “safety guardian” that ensures stable system pressure and prevents overload damage. Like an “intelligent safety valve” for the hydraulic system, it can quickly respond and precisely relieve pressure when the system pressure rises abnormally, providing core protection for the safe operation of the XE2000’s hydraulic system during high-intensity operations.

Original Factory Precise Fit, Seamless Installation

The pressure relief valve 860170901 is an original factory part exclusively developed by XCMG for the XE2000 excavator’s hydraulic system. Its design is entirely based on the layout characteristics and pressure parameters of the machine’s hydraulic pipelines. Utilizing high-precision surveying and 3D modeling technology, key details such as valve body dimensions, interface specifications, and installation orientation are precisely determined to ensure a perfect match with the hydraulic system’s pipeline interfaces. Whether it’s system integration during new machine assembly or component replacement during later maintenance, no adjustments to the piping or installation structure are required, allowing for direct “in-situ installation.” This high degree of adaptability not only reduces installation difficulty but also ensures the precise coordination between the pressure relief valve and the hydraulic system, preventing pressure relief delays or poor sealing caused by dimensional deviations from the outset.

Precise pressure relief design ensures system safety and stability

During heavy-load operation, the hydraulic system of the XE2000 excavator may experience abnormal pressure increases due to sudden load changes or pipeline blockages, posing a serious threat to core components such as pumps and cylinders. The pressure relief valve 860170901 employs a high-precision spring and valve core structure design, with a rigorously calibrated preset pressure threshold. When the system pressure exceeds the safe range, the valve core opens rapidly within milliseconds, safely releasing excess hydraulic oil back to the tank and instantly reducing the system pressure to a safe value. Its unique damping structure design effectively avoids pressure fluctuations and impacts during the pressure relief process, ensuring a smooth return of system pressure and reducing damage to hydraulic components. Meanwhile, the pressure relief valve boasts excellent reseating and sealing performance. After pressure relief, the valve core accurately resets and closes tightly, ensuring the hydraulic system returns to normal operating pressure and does not affect the continuous operation of the equipment.

High-strength materials and craftsmanship ensure superior durability

XCMG maintains strict quality control over the entire production process for the 860170901 pressure relief valve, committed to creating durable and safe components suitable for extreme working conditions. The valve body is forged from high-strength alloy steel and, after tempering and heat treatment, possesses excellent compressive strength and corrosion resistance, capable of withstanding the scouring of high-pressure hydraulic oil and the corrosive effects of the working environment for extended periods. The valve core and seat are precision ground, with the fit clearance controlled at the micron level, ensuring the sensitivity and sealing of the pressure relief action, with a service life of tens of thousands of cycles. The internal spring is made of high-temperature resistant alloy material and has undergone fatigue testing, maintaining stable elasticity even after long-term use, ensuring the accuracy of the pressure threshold. Every pressure relief valve undergoes rigorous testing, including pressure adjustment, sealing tests, and durability tests, before leaving the factory to ensure stable operation within an extreme temperature range of -30℃ to 120℃, providing users with durable and reliable safety protection.

Choosing the XCMG XE2000 excavator pressure relief valve 860170901 means choosing a solid “safety line of defense” for your equipment’s hydraulic system. With its precise original factory compatibility, sensitive pressure relief performance, and superior durability, it safeguards the XE2000’s hydraulic system in complex operating scenarios such as mining and infrastructure construction, effectively preventing equipment failure and downtime losses due to pressure overload. This ensures the equipment operates efficiently in a safe and stable state, facilitating the smooth progress of projects.
