PneuDraulics, Inc. (PDI) is a recognized leader in the design and manufacture of aerospace brake metering valves for commercial and military aerospace platforms. These valves precisely control hydraulic pressure to the braking system, ensuring smooth, reliable braking performance under all operating conditions.

Brake Metering, Emergency, and Parking Brake Solutions

PDI develops advanced brake metering valves, emergency brake valves, and parking brake valves engineered for high durability and consistent performance. Our parts minimize hysteresis to improve brake modulation, creating aerospace low-leakage hydraulic valve designs, ideally suited for parking brake applications.

Available in single or dual configurations, PDI brake metering valves can be integrated into split‑manifold architectures for rip‑stop functionality. These parts can also be supplemented with additional custom features such as:

• Thermal relief devices
• Position indicators
• Pressure switches or transducers
• Wheel de‑spin functionality

Manufacturing Quality & Performance Assurance

All PDI brake metering valves undergo automated, computerized acceptance testing to ensure precision, consistency, and long‑term reliability. Every custom part is validated to meet the stringent demands of modern aerospace hydraulic braking systems.
