Integrated Pressure Sensing and Flow Control Valve for Drone and Aircraft Engine Systems
The QXF-4A Military Aviation Sensor Single Valve is an innovative integrated component combining pressure sensing and precise flow control in a single compact unit. Engineered specifically for aircraft engine systems, drone hydraulic networks, and critical Aviation Applications, this high-performance valve provides simultaneous pressure monitoring and fluid control capabilities, reducing system complexity while enhancing reliability in demanding aerospace environments.
Manufactured with the same rigorous quality standards as our Military Metal Relay and Polarized Relay product lines, the QXF-4A represents YM's expertise in developing integrated solutions that optimize system design while maintaining uncompromising performance under extreme operational conditions.
The QXF-4A combines pressure sensing and flow control functions in a single compact unit, eliminating the need for separate components, additional piping, and multiple connection points. This integration reduces potential leak paths by 60% and decreases installation time by 40% compared to traditional separate component approaches.
Designed and tested to withstand extreme environmental conditions encountered in military aviation operations, including temperature extremes from -55°C to +125°C, high vibration environments up to 2000Hz, shock loads up to 100g, and rapid pressure transients. The unified construction provides enhanced reliability compared to systems with multiple interconnections.
Incorporates a proprietary thick-film ceramic pressure sensing diaphragm that provides excellent long-term stability, minimal hysteresis, and superior resistance to media contamination. The ceramic technology, developed through our precision manufacturing expertise, offers exceptional accuracy retention over the component's service life.
With actuation times under 4 milliseconds and pressure signal updates within 4 milliseconds, the QXF-4A provides near-instantaneous response for real-time system control and monitoring in critical aviation applications including flight controls and engine management systems.
Incorporates multi-layer hermetic sealing techniques developed through our expertise in Metal Sealing Relay manufacturing. The integrated design eliminates intermediate seals between sensor and valve functions, reducing potential failure points and enhancing long-term reliability.
Weighing under 3 grams, the QXF-4A provides both sensing and control functions without the weight penalty of separate components—critical for aircraft and drone applications where every gram affects performance, range, and fuel efficiency.
Designed to operate reliably in electrically noisy aviation environments, complementing our PCB Signal Relay and Solid State Relay products in integrated electronic control systems. Features built-in RFI/EMI protection and filtered signal outputs.
Optional smart versions include built-in diagnostics that monitor valve position, sensor health, and system integrity, providing early warning of potential issues and enabling predictive maintenance strategies.
Operating at just 0.3-0.43W for both sensing and control functions, this integrated component minimizes power draw—particularly valuable for unmanned aerial vehicles (UAVs) and other battery-dependent systems.
Critical for integrated fuel pressure monitoring and flow control in both turbine and piston aircraft engines. Provides simultaneous pressure feedback and precise fuel metering for optimal engine performance and efficiency while reducing component count and potential leak points.
Essential for compact hydraulic systems in military and commercial drones where space and weight are at a premium. The integrated design provides pressure monitoring and flow control for flight control actuators, landing gear, and payload mechanisms in a single lightweight component.
Provides integrated pressure sensing and valve control for flight control hydraulic systems, landing gear systems, and utility hydraulic functions. The unified design enhances reliability by eliminating intermediate connections that are potential failure points.
Ideal for aircraft pneumatic systems including cabin pressure control, air conditioning, and instrument air systems where integrated pressure monitoring and flow regulation simplifies system design and improves reliability.
Monitors oil pressure while providing precise flow control in engine lubrication systems, gearbox lubrication, and auxiliary lubrication circuits for optimal component protection and system performance.
Provides integrated control and monitoring for hydraulic test carts, refueling systems, and maintenance equipment where space optimization and reliability are critical for efficient ground operations.
Serves as compact backup components in critical systems where space constraints prevent installation of separate sensor and valve assemblies for redundancy.
Combining sensing and control functions in a single component reduces overall system weight by 30-50% compared to separate sensor and valve installations, while decreasing the number of individual components required by 40%.
Eliminates intermediate connections and potential leak points between separate sensor and valve components, reducing failure modes and improving overall system reliability. The integrated design provides more consistent performance over temperature and vibration ranges.
Reduces installation time by 40% compared to separate components, with fewer connections to make and verify. Maintenance is simplified with only one component to inspect, calibrate, and replace instead of multiple separate items.
The integrated design minimizes pressure drop and signal latency between sensing and control functions, providing faster, more accurate system response compared to systems with physically separated components.
Reduces the number of unique part numbers required in inventory, similar to the standardization benefits of our Automotive Relay product line. One integrated component replaces multiple separate items, simplifying procurement and logistics.
Provides system designers with more compact solutions for space-constrained applications, enabling more efficient packaging and system layout in modern aircraft and drone designs.
