Tight-tolerance machining for sealing faces and port networks on proportional valve manifolds.
Precision CNC machining keeps proportional valve manifolds flat, leak-tight, and repeatable. We hold intersecting ports and sealing faces within ±0.0015″ true position to prevent internal leakage, with 2–4 week production lead times and fast quotes.
Precision CNC Machining for Proportional Valve Manifolds
We machine proportional valve manifolds that control flow and pressure in hydraulic and electro-hydraulic systems, with dense port networks, critical sealing faces, and tight positional relationships between bores, threads, and mounting interfaces.

How We Deliver Consistent, High-Accuracy Results
Critical port networks machined in one flow to keep feature relationships and sealing faces consistent across manifolds.
Reduced handling and setups cut stack-up error, keeping parallel faces, mounting patterns, and bore centers within spec.
Process-controlled batches so first-article proportional manifolds match every repeat run, avoiding last-minute surprises before testing.
Capacity and scheduling commitments for valve manifold jobs so you get predictable lead times and fewer fire drills.
