Hello people, How can i obtain the the CV value of a control valve at 100% open, knowing the CV value at 80% open for example? Thanks "We don't believe things because they are true, things are true because we believe them." "Small people talk about others, average people talk about things, smart people talk about ideas and legends never talk." Do you think creating a CAD file for the sake of making model then importing it to STAAD and then checking it if everything sits right is a smart and time saving process? Be smart, check with the manfactures recommended method of using the vfd.

Understanding the Context

I would get a contactor that is built in with the vfd if required, that way if you have problems the vfd the manufacture would have to fix it if it fails.
