Anti-Corrosion Anodized Aluminum Hydraulic Valve Sleeve, OEM Custom CNC Machining Hydraulic System Components

Product Description

Product Description

Hydraulic & Fluid Power Core Parts are critical components for hydraulic transmission and fluid control systems, widely used in construction machinery, agricultural equipment, industrial machinery, marine and heavy-duty engineering fields. These core parts include hydraulic valves, cylinder components, pump accessories, manifold blocks, piston rods, gear parts, seal assemblies and precision fluid connectors.

Manufactured by high-precision CNC machining, grinding and honing processes, these parts achieve strict dimensional tolerance and excellent surface finish. Raw materials cover alloy steel, high-strength carbon steel, cast iron and special alloy materials. Surface treatments such as quenching & tempering, nitriding, hard chrome plating and anti-corrosion coating improve wear resistance, pressure resistance and service life under high-pressure continuous working conditions.

Strict quality inspection is carried out for pressure resistance test, leakage test, dimensional measurement and hardness testing. We support OEM and ODM custom production according to customer drawings or samples. Products comply with relevant industrial standards for heavy-load, high-pressure and harsh working-condition applications.
