Valve BLock
Hydraulic valve blocks route fluid through intersecting internal cavities, and they are machined here to tolerances down to +/-0.005 mm across multi-axis setups. NOWARUN machines custom hydraulic manifolds using 4-axis and 5-axis CNC milling centers in carbon steel, alloy steel, stainless steel, aluminum, brass, copper, or engineered plastic. Parts are produced strictly to customer drawing with specified heat treatment and surface finishing, rather than supplied from a standard catalogue.

Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Cast iron hydraulic manifolds | Billet CNC machined blocks eliminate casting porosity defects but require higher material removal during machining |
| Standard off-the-shelf blocks | Custom blocks integrate multiple valve functions into one body but require dedicated design drawings and tooling setup |
| Fabricated welded manifolds | Solid CNC milled blocks withstand much higher hydraulic pressures without risking fatigue failure at weld seams |
Use Guide
- Provide complete 2D engineering drawings with thread standards, tolerances, and surface callouts clearly marked
- Supply 3D CAD files to verify complex internal angled drillings and intersecting flow passages
- Specify operating working pressure so appropriate material and heat treatment can be confirmed
- Select surface finishing based on the operating environment to protect against corrosion
- Flush the manifold assembly prior to final valve cartridge installation to remove any environmental storage dust
