Precision-Engineered Hydraulic Valve Bodies That Perform Under Pressure

Our hydraulic valve bodies are rated from 3,000 PSI (210 bar) for standard-duty applications up to 10,000 PSI (700 bar) for high-pressure systems. Every valve body is pressure-tested to 1.5× working pressure before shipment, with test records included in the documentation package.

Our standard tolerance is ±0.005mm (±0.0002"). For critical spool bores and valve seats, we achieve ±0.001mm (±0.00004") with CMM verification. According to our CNC machining knowledge base, geometric tolerances down to ±0.010 mm are achievable when clearly indicated in technical drawings.

We commonly machine aluminum 6061-T6 and 7075-T6 for lightweight, corrosion-resistant valve bodies; 316L stainless steel for chemical and marine environments; and 17-4PH stainless steel for high-pressure, wear-resistant applications. Material selection depends on pressure, fluid compatibility, weight, and temperature requirements.

We provide hard anodizing, electroless nickel plating, passivation, and PTFE coating for hydraulic components. These treatments extend service life in aggressive fluid environments and are selected based on your operating medium and duty cycle.

CNC machining is a computer-controlled subtractive manufacturing process that uses milling, turning, or drilling to shape materials with high precision. A CAD model is converted into G-code instructions that guide cutting tools to remove material from a solid block. This makes it ideal for valve bodies because it produces tight-tolerance internal features, complex port geometries, and repeatable results from prototype to production.

Standard prototypes ship in 5-7 business days. Rush service is available in 7–15 days for urgent projects. Production volumes of 1,000+ units typically deliver within 2-4 weeks. We maintain raw material stock for common alloys to reduce lead times.

Yes. Our facility is equipped for everything from single prototype valve bodies to high-volume production runs of 100,000+ units. We use quick-change tooling and automated pallet systems to maintain efficiency at scale without sacrificing precision.

We are ISO 9001:2015 certified for quality management, AS9100D certified for aerospace applications, and ISO 13485 certified for medical devices. Our quality lab is equipped with CMM, optical comparators, surface roughness testers, and hardness testers.
