• Primary Function: Regulates cabin pressure and rate of pressure change by driving the main outflow valve assembly in aircraft environmental control systems (ATA 21).
• Dual-Motor Redundancy: Powered by dual redundant electric motors to ensure uninterrupted operation in case of a primary channel or motor failure.
• Precision Position Sensing: Integrates internal position sensors (RVDTs/potentiometers) to send real-time valve angle feedback to the Cabin Pressure Control System (CPCS).

Outflow Valve Actuator, P/N 21598-01, designed for the aircraft cabin pressurization system. It provides precise actuation of the outflow valve to help regulate cabin pressure during flight. Suitable for Embraer E170/E190 aircraft applications.
