This is a gate valve, a 300-pound valve. I’ve looked up what Z36R means; I’d like to ask what each letter in N139/A351-CF8 stands for. Also, can it be determined from this information whether the valve has purge holes?

A351-CF8 is a valve body material; SEAT/DISC: STL – the seat and disc sealing surfaces are welded with cemented carbide STL

I only know that CF8 is made of stainless steel; it’s not possible to tell anything about any purge holes from what you’ve provided

If it has a purge hole, then how should it be marked? Should it be written directly with the purge hole?

Changing the third code from 6 to 7 results in a version with a purge hole
