Dear All,
Thanks for all the input with regard to my question. Actually the wording "DUPLICATE" is specified in API Data sheet. In page 6 of API 61S data sheet, there are 3 choices for T/T/ valves. One of them is DUPLICATE type. That's why I raised this question. I think Johnny response is more...
Thanks Chicopee. I visited the web site. However what I was looking for is the Duplicate type of T/T valves or the advantages. Is the Duplicate T/T/ valves represent a quantity? Do you have any schematic of duplicate type valves or pros-cons of this type of T/T/ valves?
Thanks
Hello,
I am now busy with the evaluation of a steam turbine in the refinery project. The question that I have is that Client asked DUPLICATE Trip/Throttle valves. I would like to know what this type of valve is or if somebody can send me more information/schematic about this type of valve...
