The post How to Get the Most out of Control Valves first appeared on the ISA Interchange blog site.
The data that is really needed when selecting and sizing a control valve is rarely understood and specified, which leads to excessive variability originating from the valve. In this presentation, ISA mentor Greg McMillan discusses pervasive problems and rampant misconceptions. He then provides guidance—supported by test results—on how to select a good throttling control valve. He also explains PID tuning adjustments and a key PID feature that can be utilized to provide precise, smooth, and fast control.
