Introduction to the application and maintenance of solenoid valves and market development

– Technological innovation: In January 2025, a new pilot control system patent aims to solve the problem of solenoid valve overshoot. The system uses mechanical control to replace traditional solenoid control. By optimizing the connection between the motor and the pilot valve, the solenoid valve operation delay and fluctuation can be reduced, which can enable the excavator to control movement more finely when the load changes.

– Market development: Global infrastructure investment expansion, emerging market demand upgrades and stock equipment renewal will drive the excavator hydraulic valve market size from US$5.2 billion in 2025 to US$7.8 billion in 2030, with a compound annual growth rate of 8.4%. Among them, the market share of digital hydraulic valves will increase from 18% in 2023 to 35% in 2030 due to factors such as the popularization of 5G remote control.

– Application and maintenance: In June 2025, a Douyin video introduced that the slow movement of the excavator may be caused by the wear of the valve core of the solenoid valve group, causing the pilot oil to leak, resulting in low secondary pressure. Replacing the valve core alone can save maintenance costs.
