The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...
The Henry Pratt Company develops, manufactures and sells valves, valve actuators and control systems for use in potable water, wastewater, power, industrial, and nuclear applications. The company was founded in 1901 as a metal fabricating shop, and it designed and developed the first rubber-seated butterfly valve in 1926.

Moog also worked on several space contracts and designed part of the liquid rocket engine propulsion systems on the Voyager space probes and provided thruster valves that steered the spacecraft. Moog also made servo-actuators for four Space Shuttles. Moog provided a control and motion system for the Wimbledon Centre Court retracting roof. This ...
The systems evolved, replacing the mechanical linkages to the valves with electrical controls, producing the "fly-by-wire" design, [3] and more recently, optical networking systems called "fly-by-light". All these systems require three separate components, the hydraulic supply system, the valves and associated control network, and the actuators.
