The OS&Y (Outside Screw & Yoke) Metal Seated Gate Valve F4 is engineered for maximum operational safety, durability, and reliability in critical pipeline systems. The OS&Y design allows clear visual indication of the valve position, making it especially suitable for fire protection and safety-critical applications.

This valve features a metal-to-metal seated gate, ensuring resistance to high temperatures and prolonged compression without deformation. The seat structure provides consistent sealing performance over a long service life, even under demanding operating conditions.

The F4 short face-to-face design allows compact installation while maintaining full shut-off capability. A robust cast iron body combined with precision machining ensures mechanical strength and dependable performance.

The valve is operated via a handwheel, offering smooth and controlled operation. It is suitable for both hot and cold water systems, as well as environments where durability and operational safety are essential.
