In the remainder of this document, all the dimensions are given at their nominal value except in the case where the tolerances are indicated.
The threaded length of valve stems for which no thread length is specified is the maximum possible length.
This International Standard does not specify requirements for the caps which equip the valves, nor do the caps appear in the figures.
