Spool and Sleeve
As the core control pair of hydraulic valves, spool and sleeve directly determine the control accuracy, response speed, internal leakage and service life of the entire hydraulic system. Our proportional valve spool & sleeve products adopt precision machining and heat treatment processes, with strict micron-level tolerance control, which can perfectly replace mainly international brand original parts, and support non-standard customization. They are widely used in industrial hydraulic pressure, engineering machinery, metallurgical equipment and other fields, helping to improve the stability and energy efficiency of hydraulic systems.
