OS&Y Gate Valves

OS&Y Gate Valves

Reliable Flow Control with Visible Position Indication

The OS&Y (Outside Screw and Yoke) Gate Valve is engineered for fire sprinkler systems, providing reliable shutoff capability and clear visual indication of valve status.

Commonly used on fire protection risers, this valve design ensures the stem rises as the valve opens, allowing inspectors to easily verify whether the valve is open or closed.

The OS&Y configuration supports dependable isolation of system zones and complies with standard fire protection system requirements. Built for long-term performance, it is well-suited for commercial, industrial, and institutional fire safety applications.
