Actuators automate valves by converting an input signal into motion. This article explains the basics of electric actuator design and explores the different types of electric actuators.
Valves control the flow of a fluid through a piping system by opening, closing, or partially obstructing a flow path. All valves require actuation, which may be manual (i.e., by a person) or automated — i.e., powered by pneumatic or hydraulic pressure or by electricity. This article focuses on electric valve actuators.
