ASME Section III, Class 3 Valve W/ "N" Stamp 1

[Powerman81]

Hi,

I am working on a modification that requires the replacement of ASME Section III, Class 3 valve which requires the "N" stamp. The valve is needed for the upcoming outage that is 2 months from now. Unfortunately, the lead time for new valve is no less than 48 weeks. I am reaching out to other utilities to locate a valve that I can use. What I need to know is what process to I need to follow to qualify the new valve for my application and how long the process takes.

Thanks

Would that be "N" for Nuclear? If so, this is an uphill battle!

Your best bet is to find another plant with a surplus valve. We no longer carry our "N" stamp but even at our height when we had a "N" stamp a crazy quick delivery for a class 3 valve would have been 6 months. (typical deliveries were 12-18 months)

You can try Wier valve. They do have a "N" stamp program and I know they can turn parts for safety related valves very quickly. However I'm not sure if they can do it with full valves.
