Myth #9: Servo and proportional valves can control no more than their rated flow

摘要

Servo and proportional valves are being used increasingly in critical applications in all technical areas - marine, aerospace, industrial, and mobile. The reason is simple: They offer a superb control. One of the perceived drawbacks, however, is that they are described by a set of performance specifications that require some study to understand. I say perceived drawbacks, because arcane sounding performance specifications describe the very things that give them their control advantages and versatility over other valve types.
