Accelerate your design cycle and reduce technical risk with custom pneumatic check valves, pneumatic relief valves, precise actuation systems, and integrated flow-control solutions trusted by defense, space, and commercial aerospace leaders.

Obtain Proven Components for Mission-Critical Settings and Extreme Environments

Aerospace and defense operations require solutions that can:

• Survive the operational parameters of missions, especially when standard, off-the-shelf options fail
• Hold up to cryogenic temperatures, instances of high shock and vibration, high pressures exceeding 5,000 to 10,000 psi, and the vacuum of space
• Provide ultra-clean operation, low leakage, and long-life duty cycles
• Be supplied with short design cycles and be tailored for program-specific applications

Aerodyne Controls designs and manufactures high‑reliability pneumatic valves and flow‑control systems engineered for mission‑critical aerospace, defense, and space applications. Our portfolio includes high‑pressure valves, cryogenic valves, solenoid valves, check valves, relief valves, and integrated pneumatic assemblies built to perform in extreme environments. 

With advanced engineering, precision machining, and rigorous testing, our pneumatic components deliver low leakage, ultra‑clean operation, long‑life durability, and consistent performance across high‑pressure, high‑temperature, and cryogenic conditions. Whether supporting ECS systems, landing gear actuation, missile pneumatics, or launch‑vehicle pressurization, our hardware is trusted where reliability is non‑negotiable. 

Pneumatic Check Valves and Relief Valve

Our team is highly experienced at designing and manufacturing high-reliability check and relief valves engineered for precise flow control, backflow prevention, and over‑pressure protection in mission‑critical aerospace and defense systems.

Built for extreme pressure, temperature, and vibration environments, our pneumatic relief valves and check valves deliver low leakage, long-life durability, and ultra-clean operation across pneumatic and cryogenic architectures. 

Applications:

• Environmental control systems (ECS)

Motor-Operated Valves 

Aerodyne Controls manufactures motor-operated valves (MOVs) designed for high-precision flow control in demanding aerospace and space-flight applications. These valves provide accurate positioning, high torque output, and stable performance across wide temperature and pressure ranges, including cryogenic conditions. 

Applications:

• Propellant management systems 
• Cryogenic feed and venting 
• Pressurization modules 
• Spacecraft life‑support systems 
• High‑pressure pneumatic control 
• Engine and propulsion support systems 

Cold Gas Pressure Regulators 

Our cold-gas pressure regulators deliver stable, precise pressure control for cryogenic and high-pressure gas systems used in launch vehicles, spacecraft, and advanced defense platforms. Engineered for ultra-clean operation and extreme temperature gradients, these pneumatic pressure regulators ensure consistent downstream pressure and long-life reliability. 

Applications:

• Launch vehicle cold‑gas systems 
• Reaction control systems (RCS) 
• Cryogenic pressurization and venting 
• Spacecraft propulsion support 
• Missile pneumatic control systems 
• High‑pressure gas distribution
