Product Overview
Forged Steel OS&Y Gate Valve is a compact and robust valve designed for full open and full close operation. Gate valves are commonly used for shut-off and isolation service where minimum pressure drop is required when the valve is fully open.
The OS&Y outside screw and yoke construction provides visible rising stem movement during valve operation. This makes the valve position easier to identify while supporting reliable manual operation in high-pressure industrial piping systems.
