A seal assembly for a shaft is arranged to extend around an outer circumferential surface of the shaft and includes: a first seal ring having a first ring angled surface; a second seal ring having a second ring angled surface; and an elastic ring disposed between the first seal ring and the second seal ring and in contact with the angled surfaces. The elastic ring is arranged to act on the angled surfaces to bias the first seal ring and second seal ring radially inwardly and apart from one another. The seal assembly can be part of a rotary valve.

Seal assembly for a rotary valve

A pressure regulating shut-off valve has a valve member regulating flow of fluid between an inlet and an outlet. The valve includes a pneumatic actuator having a piston having first and second faces that define first and second volumes within a cylinder. The second face has a greater surface area than the first face. The first and second volumes are fluidly connected to the inlet, and an electrically actuated valve controls the flow of fluid along a fluid path to the second volume. The electrically actuated valve closes the fluid path, when power is supplied to the electrically actuated valve, and opens the fluid path, when power is removed from the electrically actuated valve, which causes the pneumatic actuator to act on the valve member to hold the valve member in a fixed position.

Pressure regulating shut-off valve

A Stability and Control Augmentation System ('SCAS') module comprising one or more SCAS actuators, the or each SCAS actuator comprising a mechanical component that translates rotational motion to linear motion along a first axis of said SCAS; one or more electric motors for driving linear movement of the mechanical component in response to a command signal; and one or more angular transducers to detect the position of the SCAS actuator along the first axis.
