This is not entirely true. It is, what we normally call the 3rd and 4th valves, that have the .630 bore.
The 5th valve is a quarter or 3/8 step intonation valve. It is placed earlier in the main bugle, than is the 1st valve.
Text to be read through the link, an illustration hopefully appears above here.
Please note that the link and and the picture do not refer to the same instrument.
