Cutting Taps Special Threads Standard (Screw Threads, Center Holes)Tool Selection

I will be manufacturing two different types of bicycle parts with "5V2" and "CTV5-36" threads. Can you please tell what the difference between these two threads?

"5V2" and "CTV5-36" threads are specified in "JIS D 9422 Bicycle Tire Valve Threads".
They have a similar major diameter (about φ5.3), but there is a difference in application.
There are two types of hand taps for bicycle tire valve threads, HT CTV P2 5V2 and HT CTV P3 CTV5-36 and both have 1.5P chamfer.
