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 ...
Electric rotary valve actuator controlling a butterfly valve. A rotary actuator is an actuator that produces a rotary motion or torque. The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators are electrically powered; others may be powered pneumatically or hydraulically ...
Protech Instruments & Systems, an instrumentation company, was purchased in 1985 to expedite the development of Pakscan, a digital bus control system for actuators. [6] In 1999 it bought Fluid System Srl, an Italian actuator business, in 2000 it bought Skilmatic in Leeds [6] and in 2002 it acquired Jordan Controls, a United States actuator ...
Pneumatic valve: Actuated using a compressible medium like air, hydrocarbon, or nitrogen, with a spring diaphragm, piston cylinder or piston-spring type actuator; Hydraulic valve: Actuated by a non-compressible medium such as water or oil; Electric valve: Actuated by an electric motor; A wide variety of valve types and control operation exist.
Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as ...
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.
