What does NGBPR mean? Some valves are labeled GBPR – by the way, what is the difference between them?

I would like to ask what NGBPR means in the specifications for valves: GATE VALVE, BB, OS&Y, CL300 (PN5.0MPA), RF, ASTM A182 F321; Trim: STL, Stem: A182 F321, Packing: NGBPR, Gasket: Ni-Base Alloy/Thermiculite or ThermaPur SWG, BOLT. Some valves use GBPR instead – what is the difference between them? The New Year is approaching; wish everyone a happy New Year!
Someone has asked this question before; it can be found here: https://bbs.hcbbs.com/thread-713932-1-1.html. GBPR = graphite braided packing ring, that is, a graphite-woven packing ring
What does NGBPR mean in this context?

Welcome more participants to engage in discussions on the forum. Happy New Year!
I’m wondering whether the N in NGBPR stands for normal or non
Nickel-based alloys and flexible graphite + rings
