Precision CNC Machining for Proportional Valve Housings

Precision CNC Machining for Proportional Valve Housings

Tight-tolerance machining for complex port networks and sealing faces.

Precision machining of proportional valve housings held to ±0.001″ on critical bores and faces. We deliver consistent feature alignment across production runs, fast quoting, and predictable lead times—eliminating leakage, spool binding, and last-minute engineering fire drills.

Precision CNC Machining for Proportional Valve Housings

We machine billet proportional valve housings requiring accurate port geometry, flat sealing faces, and tight positional relationships between bores, cavities, and mounting features.
