Thank you for the search you've done for me, this explains a lot anyway. Is there any good tradition on this forum how a user can thank well in return ? Can I do anything else ?
Dear team !
Can you please advise what does "RF R9 flange" mean ?
I can understand RF (raised face) but I couldn't have found any information on R9 in the ASME standards
Thank you🤝
Thank you for the tip LittleInch,
This is a good idea on an isolation valve. Our valve is just VPR-2 (GE tag)
I believe, this part of my so called calculation is total mess [bigsmile]
3. Multiply the rated capacity Q by the leakage factor in accordance with EN 60534-4
Factor for Leakage class...
Thank you for your help and detailed explanation. Unfortunately, the problem is that we don't have any detailed specification for this valve. Anyways, you response is highly helpful !
Hi Team ! Glad to meet you all and hope I won't disturb you a lot.
I don’t even have a technical education, but I'm in a situation where I was forced to understand the leak class and calculation method myself. I wasted my job vacation for this lol and really hope and beg you to help, thank you ...
