The full name of an OS & Y valve is

Explanation:
OS&Y stands for Outside Stem and Yoke. This name describes a valve design in which the stem and the supporting yoke are visible on the outside of the valve body, making the valve’s operation and position easy to observe and verify during inspections. The other options either use terms that aren’t part of the standard acronym (on-site, outer) or contain a misspelling (yolk) or an incorrect descriptor (over-stem). The correct form directly reflects the physical arrangement of the stem and yoke outside the valve.
