The Nerve Center of Hydraulics: A Guide to High-Precision Valve Bodies

In contemporary fluid power, the Valve Body contains the nerve center. As an engineer, knowing the relationship between Material and Precision Machining is essential.

Material & Structure In search of the internal density that makes a Valve Body possible. Ductile Iron = vibration damping Forged Steel = high pressure integrity Angled and process holes create a compact structure and a smooth flow of fluid to reduce pressure drop.

Micron-Level Precision: The contact area between the spool and body is demonstrated here. The precision of Machining Centers and Hoing machins produce bore tolerances of ± 0.002mm. This is important for the proper operation of Cartridge Valves, as it defines the friction-free movement of the spool and the low system internal leakage.

The Difon Standard "Success comes from chamfering; failure comes from burrs." All Custom Hydraulic Manifolds are 100% checked with Leader CMM in our Constant Temperature Inspection Room, errors caused by thermal expansion are eliminated. Our special finishing removes burrs from cross-holes, preventing tiny lethal particles that threaten the system.
