Electric Valve Actuators: An Alternative to Air
The choice depends on the application, amount of control required, and available power source
Increased use of computers and programmable logic controllers (PLCs) in process control systems represents a major operational change in many plants. This change must be addressed in choosing the right valve actuator for a specific application.
Many plant engineers are discovering that the technology employed by electric actuators often offers distinct advantages over traditional pneumatic types in new control systems. An analysis of both electric and pneumatic actuators helps in choosing between the two. ...
