Abstract: A valve assembly including a valve body with an inlet port and an outlet port, a flow passage and a valve element disposed within the flow passage, an actuator and a lockout mechanism configured to maintain the position of the valve assembly in an opened position or a closed position. The lockout mechanism can include at least one screw.

Abstract: A method and apparatus for predicting conditions favorable for icing, includes sensing a value indicative of a thermal cycling period, comparing, the sensed thermal cycling period with a threshold value, determining, if the sensed thermal cycling period satisfies the threshold value, and indicating, by the controller module, that conditions favorable for icing are present when the sensed thermal cycling period satisfies the threshold value.

Abstract: A valve assembly for use in a bleed air system or any other pneumatic, hydraulic, mechanical, magnetic, or electrical system that includes a valve assembly. The value assembly includes a valve housing, a valve member, a pressure regulator, and a position sensor assembly. The valve housing includes an inlet and outlet that is angled from the inlet. The valve member slides between a first position wherein the valve member is closed and abuts a seat within the valve housing and a second position wherein the valve member is in a position a distance away from the seat.
