Product Description
The 303556-01 is a pneumatic air valve that regulates compressor airflow and pressure in aircraft environmental control systems. This valve routes or blocks bleed air from the engine compressor stage to cabin pressurization, heating, and cooling circuits. Constructed from aluminum body with stainless steel internals for corrosion resistance in high-temperature pneumatic environments.
The valve responds to system pressure signals and pilot air inputs to modulate flow rates. Installation requires verification against the aircraft Illustrated Parts Catalog and compliance with manufacturer maintenance procedures. SAE Aerospace Standards AS1066, AS1214, and AS1225 govern pneumatic valve specifications.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
