Hydraulic valve blocks are the core assembly carriers of hydraulic and pneumatic transmission systems, undertaking the functions of medium shunting, pressure regulation and pipeline connection inside fluid equipment. The square aluminum valve blocks shown in the picture are finished products processed by high-precision CNC milling, featuring integrated internal thread holes, through flow channels, mounting fixing holes and positioning grooves, which are widely applied to hydraulic stations, industrial valve assemblies, automation fluid circuits and mechanical power systems.

This type of integrated valve block abandons the traditional scattered pipeline layout, concentrating multiple oil passages and thread interfaces on a single aluminum matrix. Adopting one-time clamping processing technology on CNC machining centers, all deep flow holes, precision internal threads, assembly holes and positioning structures are formed at once. The smooth inner wall of the runner effectively reduces fluid flow resistance and medium turbulence; standardized precision threads are strictly inspected with thread gauges to ensure tight connection and effectively prevent oil leakage under long-term high-pressure working conditions.

We select high-quality 6061 aluminum alloy blanks as raw materials for valve block production. The material has moderate structural strength, good pressure bearing capacity and excellent machining performance, while its lightweight property can effectively control the overall weight of hydraulic equipment. According to customers’ usage environments, we can support subsequent surface treatments such as natural anodizing and hard anodizing. Anodized film can improve the oxidation resistance and wear resistance of the valve block surface, avoiding corrosion failure caused by hydraulic oil and humid working environments.

Our factory provides full-process customized services for hydraulic valve blocks. We can complete processing according to customers’ 2D drawings and 3D model files, covering prototype trial production, small-batch verification and mass stable delivery. Each finished valve block will pass multi-dimensional detection including hole position accuracy, thread qualification and runner smoothness to ensure stable and consistent product quality in each batch.
