UL FM Approved OS&Y Flanged Gate Valve

Product Description

This UL & FM approved OS&Y Gate Valve is a high-reliability isolation valve designed for fire protection systems, sprinkler networks, and industrial water supply applications. The outside screw & yoke (OS&Y) rising-stem design provides clear visual indication of valve status, making it ideal for life-safety and critical infrastructure installations.

The valve body is manufactured from high-strength ductile iron and coated with fusion-bonded epoxy (inside & outside) for long-term corrosion resistance. Stainless-steel stem construction ensures stability and durability under high pressure and demanding working environments. Suitable for commercial buildings, industrial facilities, fire pump rooms, hydrant systems, and water-based fire suppression networks.
