Dual-actuator aircraft environmental control system valve

A regulator valve includes dual actuators that operate according to different principles to position a valve element to either an open or a closed position. One actuator, which is an electromechanical actuator, operates in response to electrical command signals. The other actuator, which is a pneuma...

Beschreibung
Zusammenfassung:	A regulator valve includes dual actuators that operate according to different principles to position a valve element to either an open or a closed position. One actuator, which is an electromechanical actuator, operates in response to electrical command signals. The other actuator, which is a pneumatic actuator, operates in response to a fluid pressure. The electromechanical actuator is responsive to the electrical command signals to rotate in either a valve open or a valve close direction, to move the valve element to either the open or closed position.
