Description
The OS & Y Gate Valve is a high-quality isolation valve designed for safe, reliable, and long-lasting performance. Featuring an externally mounted rising stem, the valve provides a clear visual indication of whether it is open or closed, making it ideal for applications where quick inspection is critical.
Widely used in fire fighting systems, sprinkler installations, water supply pipelines, and industrial pipelines, the outside screw design keeps the stem threads away from the fluid, reducing corrosion, wear, and maintenance needs. The robust cast iron or ductile iron body and stainless steel or bronze stem ensure durability under high-pressure conditions. The wedge-type gate delivers tight shut-off performance with minimal pressure loss.
Compliant with NFPA and international standards, this valve is perfect for commercial, industrial, and residential fire protection systems, offering reliable operation and long service life.
