Actuator selection and sizing for valves SpringerLink
2019年9月12日 An actuator is a machine or component installed on the top of an industrial valve for automatically moving and controlling the valve. The performance of a valve is largely dependent on its actuator. Three factors are important for engineers to consider when selecting an actuator: frequency of operation, ease of access, and critical

Basic Guidelines for Control Valve Selection and Sizing
2 之 Ideally the control valve response should be linear (from the control system’s perspective). If the PID output changes 5%, the process should respond in a similar fashion regardless of where the output is. (In other words 15% to 20% or 85% to 90% should ideally generate the same process response.) If the valve response is non-linear, control
