Precision hydraulic solenoid valves
EDOUN integrates design, high-volume production, and rigorous testing under one roof in our Jinzhong facility. We deliver zero-leakage performance for global heavy machinery OEMs and industrial distributors.
Automated CNC machining lines
Our Jinzhong manufacturing base utilizes multi-axis CNC machining centers to achieve micron-level tolerances. Every valve body is machined from forged steel to withstand continuous-duty cycles under extreme pressure.
Micron Tolerances
Forged Steel
Automated Assembly
High-precision machining centers drill and hone internal valve chambers to exact dimensional specifications, ensuring smooth spool movement and zero-leakage performance.
Robotic assembly lines wind copper solenoids and fit internal components with absolute repeatability, eliminating human variance in high-volume production runs.
We source premium raw materials to forge heavy-duty valve bodies, preventing structural fatigue and deformation under continuous high-pressure operations.
Rigorous wet-loop pressure testing
We do not rely on statistical batch sampling. Every single hydraulic solenoid valve undergoes comprehensive wet-loop testing on our custom-built diagnostic rigs before leaving the Jinzhong facility.
