Class 150 Gate Valves are designed for reliable isolation service in pipelines where unrestricted flow and minimal pressure loss are required. Featuring a robust cast steel construction, flexible wedge disc, and OS&Y (Outside Screw & Yoke) design, these valves provide dependable shut-off performance and long operational life. When fully open, the gate is completely withdrawn from the flow path, allowing smooth and unrestricted fluid movement. These valves are ideally suited for on-off applications in oil & gas, chemical processing, water treatment, power generation, pharmaceutical plants, and various industrial piping systems.
