Our Precision Hydraulic Valve Spools & Sleeves are engineered for demanding hydraulic and pneumatic applications where accuracy, sealing quality, and reliability are critical. Manufactured using advanced CNC turning, grinding, honing, and precision polishing processes, each component offers exceptional dimensional stability with micron-level tolerances.
Constructed from high-strength alloy steel, stainless steel, or custom-specified materials, these valve spools and sleeves deliver outstanding wear resistance, corrosion protection, and long service life. Their optimized structural design—including precision grooves, flow channels, and sealing surfaces—ensures low friction, minimized leakage, and smooth, stable fluid control.
Every spool and sleeve undergoes a rigorous quality inspection process, including roundness measurement, surface roughness testing, concentricity checks, and hardness verification. This guarantees consistent performance and perfect fit in hydraulic valves, proportional valves, servo valves, pneumatic actuators, automotive transmission systems, and industrial automation equipment.
We offer fully customized solutions based on drawings or samples, supporting complex geometries and special material requirements. Whether for mass production or prototyping, our manufacturing capability ensures accuracy, consistency, and fast delivery for global OEM and industrial clients.
