HU87506 is a precision-manufactured aerospace engine fuel system pressure regulator component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core pressure control part in the engine fuel system, adjusting the pressure of aviation fuel delivered to the combustion chamber according to the engine's operating status, which is critical for matching the fuel supply with the air intake volume, ensuring sufficient and stable combustion, and maintaining the engine's thrust output balance during different flight conditions.

Made from high-strength, fuel-resistant stainless steel with anti-corrosion treatment, it withstands operating temperatures from -60°C to 240°C and long-term contact with aviation fuel. Weighing 0.28kg with a precision-machined pressure adjustment structure, it allows for fast calibration and pressure accuracy testing during fuel system MRO overhauls. FAA Part 25 certified, it is a key component for fuel system operational stability.
