"Operating signal converter" of a hydraulic system
Although the pilot valve does not directly provide high-pressure power, it is crucial for the excavator's "human-machine interaction," with specific functions including:
1. Signal Conversion: Converting the mechanical displacement of the operating handle (such as pushing, pulling, or cranking) into pressure changes in the pilot hydraulic oil (0.5-4MPa), forming a control signal.
2. Precise Control: By adjusting the output pressure and flow rate of the pilot oil, precisely controlling the valve opening of the main hydraulic valve, achieving "stepless speed regulation" of the actuator (such as slow digging and rapid lifting of the bucket).
3. Safety Protection: Some models integrate a relief valve function, automatically releasing pressure when the pilot system pressure exceeds a set value (usually 5MPa) to prevent damage to control components due to excessive pressure.

Small Tips
Extend the lifespan of the "Pilot Valve Assembly"
Strictly select pilot oil
Low-viscosity pilot hydraulic oil (such as ISO VG 32 pilot oil) that meets the requirements of the machine model must be used. Mixing with main hydraulic oil is prohibited (high viscosity can easily cause valve core sticking). The pilot oil should be changed every 2000 hours.
01
Replace the filter regularly
The pilot oil filter element needs to be replaced every 1000 hours. In environments with a lot of dust and impurities (such as mines or demolition sites), the replacement time should be shortened to 600 hours to prevent impurities from entering the pilot valve.
02
Clean the pilot valve regularly
Disassemble the pilot valve every 3000 hours and clean the valve core and oil passages with clean diesel (or a special hydraulic system cleaner). After cleaning, blow it dry with compressed air to avoid residual cleaner affecting the performance of the hydraulic fluid.
03
Check the connecting parts
Inspect the connection between the handle linkage and the pilot valve monthly, tighten any loose pins and nuts, and apply a small amount of grease (such as lithium-based grease) to the moving parts of the linkage to reduce mechanical wear.
