FAQ


Q: What operational behavior usually indicates valve-related hydraulic issues?
A: Jerky movement, delayed boom response, uneven actuator speed, or abnormal pressure fluctuation during combined operations.
 
QWhy is valve contamination considered a major failure source?
A: Fine debris inside hydraulic oil can interfere with spool movement and disrupt accurate pressure control.
 
QWhat should be verified before replacing the control valve?
A: Hydraulic line cleanliness, pressure calibration status, and compatibility with the machine control circuit.
 
Q: Can a worn valve reduce overall digging efficiency?
A: Yes, unstable oil distribution directly affects force output and movement coordination across working functions.
 
Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
