Does anyone have experience at applying for a CRN (Canadian Registration Number) for Cat C valves that are B16.34 design but are made from a material that is not listed in B16.34?
I know that there are two options:
1) Burst Proof Test witness by Third Party
2) Detailed engineering Calculations...
I work for a valve manufacturer and we sell valves with Sambo gears on them. I have not experienced any difficulties with them and find that they are a good quality product.
Attached is some info that I had on Sambo gears...not sure how old it is, but it might be of some help to...
