2C14742G04 is a precision aerospace component compliant with AS9100D quality standards and FAA/EASA aviation regulations, dedicated to aircraft engine hydraulic actuation systems.It acts as a high-performance hydraulic servo valve, a core control component for precise motion regulation during MRO assembly. It accurately converts electrical control signals into proportional hydraulic flow and pressure outputs, enabling precise adjustment of engine variable geometry components, thrust reversers and actuation mechanisms, ensuring optimal engine performance across all flight phases and operating conditions.Made of aviation-grade corrosion-resistant alloy with precision spool and sleeve assemblies, it resists high pressure and hydraulic fluid erosion, working stably at -55℃ to 210℃. Weighing 0.22kg, it features compact structure, high response speed and reliable sealing performance. It is a critical component to guarantee engine actuation accuracy and overall aircraft flight safety and operational reliability.
