Turbine Inlet Control Valve Repair & Overhaul
FAA & EASA certified turbine inlet control valve repair and overhaul.
About the Turbine Inlet Control Valve
A turbine inlet control valve regulates the air supplied to the turbine inlet of an air cycle machine, controlling expansion across the turbine and thereby the cooling output of the environmental control pack. By metering inlet flow and pressure it governs turbine speed and discharge temperature, helping maintain target cabin and avionics conditions while protecting the air cycle machine from overspeed. As a pressure-regulating valve in the air management system it sits directly upstream of a rotating cooling component. Repair and overhaul are driven by butterfly or poppet wear, actuator and regulator drift, spring fatigue, seat and seal erosion causing leakage, thermal distortion from high-temperature air, and contamination-induced sticking that destabilize turbine control, degrade cooling performance, or risk improper turbine inlet conditions.
