Hydraulic Valves

PneuDraulics, Inc. (PDI) designs and manufactures aerospace hydraulic valves and aircraft hydraulic system components for commercial and military platforms. Our portfolio includes aerospace hydraulic utility valves, hydraulic control valves, flow regulating valves, auxiliary hydraulic valves, and aircraft hydraulic pressure control valves designed to manage flow, pressure, and system safety in demanding flight environments.

PDI manufactures brake metering valves, thrust reverser control valves, landing gear selector valves, flow control valves, balanced relief valves, parking brake valves, secondary hydraulic valves, and low-leakage hydraulic valves engineered for high-pressure operation. We also produce shuttle valves, priority valves, pressure priority valves, hydraulic flow regulators, hydraulic timing valves, heat exchange valves, hand pump valves, self-setting valves, and high-pressure hydraulic valves for primary and secondary aircraft systems.

For line protection, PDI offers hydraulic fuses with bypass capability and hydraulic velocity fuses that safeguard critical circuits in the event of pressure loss or line rupture.

All PDI aerospace hydraulic valves are rigorously tested to meet current aerospace standards for safety and reliability.

PDI hydraulic valves are used worldwide on major commercial and military aircraft platforms. Aerospace customers rely on PDI for precision-engineered hydraulic pressure control valves and advanced flow management solutions.

If you are looking for aerospace hydraulic valves or aircraft hydraulic pressure control solutions, contact PDI for expert support and a quote. PDI is your trusted partner for aerospace hydraulic system components.

Valve Types

Brake Metering Valves
Brake metering valves port system pressure to the aircraft brakes based on manual handle input for both primary and emergency braking. These aircraft hydraulic pressure control valves regulate braking force and set park brake pressure in the fully actuated position with minimal leakage.

Fuses
Hydraulic fuses are aerospace auxiliary hydraulic valves designed to shut fluid flow off when a hydraulic line fails. These aerospace self-setting valves protect essential hydraulic capabilities and reduce the potential for system pressure loss and fire hazards.

Priority Valves
Priority valves are high-pressure aerospace flow regulating valves that direct hydraulic flow to critical subsystems regardless of downstream pressure conditions. Also referred to in some configurations as balanced relief valves, they ensure availability of essential aircraft systems during peak demand.

Shuttle Valves
Shuttle valves are hydromechanical aerospace flow control valves that allow two independent hydraulic sources to supply downstream components. These aircraft flow control valves maintain separation between pressure sources, increasing system reliability and redundancy.
