Proper actuator sizing for rotary control valves: Part 1

摘要

In the sizing of rotary control valves, cost pressure leads to the actuators being sized with the lowest possible safety factors so that smaller actuator sizes can be used. The problem is that no applicable sizing standards to guarantee reliable actuator sizing exist. This results in the actuators being either oversized or undersized. This first part of the article, will show how rotary valves can be sized reliably.
