Valve actuators drive the movement of valves either in on/off, modulating or control service. These actuators can be powered manually, pneumatically, hydraulically or electrically. For electric actuators, there is a great, educational YouTube series, Introduction to Valve Actuation and Electric Actuators.

The 10 videos range from 2 minutes to 8 ½ minutes and feature these topics:

1. Introduction to Valve Actuation and Electric Actuators (5:09)
2. Introduction to Electric Actuator Operation (4:37)
3. Introduction to How Stroke and Thrust is Created (2:04)
4. Introduction to Electric Actuator Design for a Range of Valve Sizes (3:22)
5. Introduction to Non-Intrusive Versus Conventional Style Electric Actuator Design (3:29)
6. Introduction to Electric Actuator Motors & Duty Cycles (8:34)
7. Introduction to Variable Speed in Electric Actuation (4:29)
8. Introduction to Electric Actuator Fail Safe Functionality (8:32)
9. Introduction to Electric Actuator Setup, Control, and Monitoring (6:38)
10. Introduction to the Bettis Electric Actuator Portfolio (7:16)

Here’s the playlist of the full series if you’d like to learn more about electric valve actuation.
