The abbreviation OS & Y stands for which valve description?

Explanation:
OS&Y stands for Outside Stem and Yoke, describing a valve where the stem and yoke are located outside the valve body. This exterior arrangement makes the valve’s position easy to read at a glance and allows simple application of lockout devices, which is especially helpful in fire protection where quick verification of a valve’s status is important. The other phrasings aren’t standard terms and would imply different, non-existent configurations, so they don’t fit.
