High-Performance Flow Control Valve for Drone and Aircraft Engine Applications


The T-5T Military Aviation Valve is a precision-engineered flow control component designed for reliable fluid and gas management in demanding aerospace environments. Engineered specifically for aircraft engine systems, drone hydraulic networks, and critical Aviation Applications, this high-quality valve provides precise flow regulation, pressure control, and system isolation essential for optimal performance and safety.
Manufactured with the same rigorous standards as our Military Metal Relay and Polarized Relay product lines, the T-5T represents YM's commitment to producing flow control components that deliver exceptional reliability and performance under extreme operational conditions.
Designed and tested to withstand extreme environmental conditions encountered in military aviation operations, including temperature extremes, high vibration environments up to 2000Hz, shock loads up to 100g, and rapid pressure fluctuations. The rugged construction maintains operational integrity under conditions that would compromise commercial-grade valves.
Features precision-machined internal components and optimized flow paths for accurate flow regulation across the entire operating range. The valve provides consistent performance with minimal pressure drop and precise metering capabilities.
Incorporates multi-material sealing systems developed through our expertise in Metal Sealing Relay manufacturing. The combination of elastomeric and metal seals ensures leak-free operation throughout the valve's service life, even after extensive cycling.
Weighing under 3 grams, the T-5T provides robust flow control functionality without significant weight penalty—critical for aircraft and drone applications where every gram affects performance, range, and fuel efficiency.
With actuation times under 4 milliseconds, this valve responds instantly to control signals, ensuring immediate system response for flight control, engine management, and emergency systems.
Designed to operate reliably in electrically noisy aviation environments, complementing our PCB Signal Relay and Solid State Relay products in integrated electronic control systems without interference.
Operating at just 0.3-0.43W, this valve minimizes its own power draw—particularly valuable for unmanned aerial vehicles (UAVs) and other battery-dependent systems where every watt of power consumption matters.
Constructed from materials specifically selected for resistance to aviation fluids including Skydrol hydraulic fluid, jet fuels, de-icing compounds, and salt spray environments, ensuring long-term reliability.
Critical for fuel flow regulation, fuel shutoff, and fuel transfer operations in both turbine and piston aircraft engines. Provides precise control for optimal engine performance and fuel efficiency.
Essential for hydraulic pressure control in flight control systems, landing gear actuation, and payload mechanisms in military and commercial drones. The lightweight design preserves flight endurance while delivering reliable control.
Monitors and controls pressure in flight control hydraulic systems, landing gear systems, brake systems, and utility hydraulic systems in both military and commercial aircraft platforms.
Provides precise air flow control for aircraft pneumatic systems including cabin pressurization, air conditioning, anti-icing, and instrument air systems.
Controls oil flow in engine lubrication systems, gearbox lubrication, and auxiliary lubrication systems for optimal component protection and system performance.
Provides reliable flow control for aircraft refueling systems, hydraulic test carts, maintenance equipment, and ground-based test systems.
Provides precise, reliable flow control essential for system performance and safety, reducing operational risks and unscheduled maintenance events that can ground aircraft and disrupt operations.
Extended service life (10,000+ cycles) and minimal maintenance requirements lower total cost of ownership compared to valves requiring frequent replacement, recalibration, or overhaul.
Precise flow control enables optimal system operation, reducing unnecessary fuel consumption and improving overall aircraft efficiency—particularly valuable for commercial operators and military fleets.
Standardized designs compatible with multiple system types reduce the number of unique valve components required in inventory, similar to the standardization benefits of our Automotive Relay product line.
The T-5T Military Aviation Valve is designed and manufactured to meet or exceed the following standards:
All materials are certified for aviation use with full traceability documentation available for quality audits and regulatory compliance verification.
The T-5T is manufactured in YM's temperature-controlled production facilities using CNC machining centers with micron-level accuracy. Our manufacturing process incorporates statistical process control to maintain tight tolerances and consistent quality across production batches.
Every valve undergoes rigorous testing and validation:
Critical valve assemblies are performed in Class 100 clean rooms to prevent contamination that could compromise valve performance or service life in sensitive aerospace applications.
Verify that the T-5T pressure rating, temperature range, flow capacity, and media compatibility match your system requirements. Check port thread compatibility and electrical specifications.
Ensure all system components are clean and free from contamination. Use appropriate thread sealant or sealing washers as specified. For systems incorporating PCB Board Relay components, ensure proper electrical isolation.
Install the valve using appropriate torque values for your specific port configuration. Avoid overtightening which can damage sealing surfaces. Ensure proper alignment to avoid stress on valve body.
Connect the valve solenoid according to wiring diagrams. Ensure proper voltage supply and protection circuits are in place. For systems with multiple valves, ensure proper addressing and control sequencing.
Conduct system pressure tests and functional verification. Cycle the valve through its full operating range to ensure smooth operation and verify no leakage at all connection points.
Under standard operating conditions, the T-5T is designed for a minimum service life of 5,000 flight hours or 10,000 actuation cycles, whichever comes first. Many installations exceed these minimum expectations in field applications.
