What does OS&Y stand for in valve terminology?

Explanation:
OS&Y stands for Outside Screw and Yoke. This describes a valve where the screw threads that move the stem are on the outside of the valve body and the yoke is external. Because the screw and yoke are visible, you can easily observe the valve’s stem movement, which helps indicate whether the valve is open or closed and allows straightforward maintenance access. The other phrases aren’t standard terms in valve terminology, so they don’t fit the established naming convention.
