Class 900 Gate Valves are engineered for high-pressure isolation services where reliable shut-off, full flow capacity, and long-term durability are essential. Designed with a full-bore OS&Y (Outside Screw & Yoke) configuration and flexible wedge gate, these valves ensure bi-directional sealing and minimal pressure loss across the pipeline. The heavy-duty cast steel body, welded seat rings, and precision-machined sealing surfaces provide dependable performance under demanding operating conditions. Suitable for both standard and cryogenic applications, these valves are widely used in oil & gas, petrochemical plants, refineries, power generation facilities, and critical industrial process systems.
