OS & Y Gate Valve

96 products found

OS & Y (Outside Screw and Yoke) Gate Valve is designed with an external rising stem that clearly indicates valve position, making it ideal for safety-critical industrial applications. The OS&Y structure keeps the stem outside the pressure boundary, improving sealing reliability and simplifying maintenance. It is widely used in fire protection systems, oil and gas pipelines, water supply, and power plants. Available in cast iron, ductile iron, carbon steel, and stainless steel, it provides tight shutoff and durable performance. Our platform features trusted OS & Y Gate Valve manufacturers in China, offering compliant and application-specific solutions.
