Introduction to Valve Actuation and Electric Actuators

Introduction to various valve types, actuation technologies, and electric actuators specifically.

Part 2: Basic overview of how electric actuators work internally and with external gears. How output torque/thrust and speed is created to meet application needs.

Part 3: Overview of how multi-turn, quarter-turn, and linear motion is created by electric actuators in order to operate various valve types.

Part 4: Overview of how electric actuators in the Bettis electric portfolio are designed to fit a broad range of valve sizes from compact actuators to full featured units.

Part 5: Introduction to Non-Intrusive Versus Conventional Actuators

Part 6: Overview of types of motors used in electric actuators as well as actuator performance ratings for on/off, modulating, & continuous modulating services. Examples of each service type are discussed.

Part 7: Overview of new variable speed technology now available in electric actuators. Discussion of various configuration possibilities specific to the Bettis RTS electric actuator.

Part 8: Overview of fail-safe functionality and various approaches to achieve a fail-safe stroke on loss of power. Discussion of SIL ratings for electric actuators and SIL capabilities of electric actuators in the Bettis electric portfolio.

Part 9: Overview of various approaches to electric actuator setup, control, and monitoring.

Part 10: Overview of the Bettis electric actuator portfolio including software and network master.
