  "definition": "An abbreviation for Outside Stem and Yoke, a type of gate valve commonly used in fire protection systems. The valve's stem rises and falls with the gate, providing a visual indication of whether the valve is open or closed. This design is preferred for fire sprinkler systems because its external stem clearly shows the valve's operational status.",
