Abstract
A valve assembly for a turbine engine includes a valve arranged in an air flow path. The valve has a shaft. The valve is movable between an open position and a closed position. An electric actuator is coupled to the shaft and is configured to move the valve between the open position and the closed position. A thermal barrier is arranged between the valve and the electric actuator.

A valve assembly for a turbine engine, comprising:
- a valve arranged in an air flow path, the valve having a shaft, the valve movable between an open position and a closed position;
- and
- an electric actuator coupled to the shaft and configured to move the valve between the open position and the closed position, wherein a housing thermal barrier is arranged between a valve housing and electric actuator housing;
- wherein the shaft comprises a first shaft portion that is attached to the valve and a second shaft portion attached to the electric actuator, wherein a shaft thermal barrier is arranged between the first and second shaft portions, said shaft thermal barrier moving with said first and second shaft portions and being within the electric actuator housing;
- and
- said housing thermal barrier and said shaft thermal barrier being formed of at least one of titanium or a ceramic material and the valve, the valve housing and the electric actuator housing are formed of distinct materials.
