HU55230 is a precision aerospace component compliant with AS9100D quality standards and FAA/EASA regulations, dedicated to aircraft engine pneumatic and hydraulic control systems.It acts as a high-reliability solenoid valve, a core on-off control component for MRO replacement. It precisely switches fluid or air circuits per engine control unit signals, regulates the flow of pneumatic pressure or hydraulic oil for key actuators, ensures fast and accurate response to control commands, maintains stable system operation under variable flight conditions, prevents circuit blockage or leakage, and avoids malfunction of engine control mechanisms.Made of aviation-grade corrosion-resistant alloy with sealed coil structure, it resists vibration, high temperature and medium erosion, working stably at -55℃ to 220℃. Weighing 0.13kg, it features compact design, low power consumption, standardized connection ports and reliable sealing, enabling easy installation and long-term stable operation. It is a critical component to guarantee engine control accuracy and overall operational safety and reliability.
