"D body" or "ET Body"...!!!....??? 2

[hot2000]

Hello All,
Could somebody explain me what is the difference between "D Body" and "ET Body" valves? Where are they used? Which one is best for gas pressure controlling, which one suits liquid? How can they be sized and how can an engineer decide to put most suitable place?
thanks!!

The Fisher book is available for FREE as a .pdf file (Adobe Acrobat) on the Fisher website:

http://www.documentation.frco.com/groups/public/documents/book/cvh99.pdf

I recommend that you download the file for your future daily use as followsthe above URL takes you there, but you can't save the file). Instead,

1. Go to

http://www.documentation.frco.com/groups/public/documents/web_resources/wui_query_page.hcst

2. Do a “search” for “control valves”

3. You will get a listing of information that you can't imagine! And you will find the Control Valve Handbook in that listing also. Right click on the subject Handbook hyperlink and choose “Save as” and the rest is your engineering property in the Hard drive folder of your choice.

For your further engineering strength and know-how, read and study this information with the assurance that it will open up and shed light on areas of process control that you may have never even thought you would dominate. This information is pivotal to giving you the confidence and assurance that you can control virtually any fluid process with simple knowledge and know-how. This stuff was never taught in university in my time and I doubt that it is being taught today either. There simply is not enough curriculum time or hands-on, experienced profs.

With this information in hand, you will have the answers to your queries.
