OS&Y Resilient Seated Gate Valve
The Blaze BT 1406 OS&Y Resilient Seated Gate Valve is designed for reliable isolation in high-pressure water systems. Featuring an Outside Screw & Yoke (OS&Y) design, it provides clear visual indication of valve position, making it ideal for fire protection and critical infrastructure systems. Built to BS 5163 standards, and WRAS approved, this valve ensures long-term durability and safe operation in potable water networks. It is fully Fusion Bonded Epoxy (FBE) coated internally and externally, providing excellent resistance to corrosion and harsh environments.
