856A3604P01 is a high-precision aviation pneumatic component compliant with AS9100D standards and FAA/EASA airworthiness regulations, engineered for pressure relief and flow protection in aircraft pneumatic bleed air systems during MRO and assembly. Fabricated from lightweight, corrosion-resistant aluminum alloy with hard anodized coating, it operates stably across extreme temperatures from -60℃ to 250℃, resisting high-temperature bleed air corrosion, pressure surges and cyclic fatigue without performance degradation. Its precision-machined relief valve ports ensure seamless, leak-free integration with pneumatic pipelines, eliminating overpressure risks during engine start-up, climb and cruise phases. Compact and reliable, it optimizes bleed air system safety and serves as a critical part for aircraft operational stability and engine protection.
