Class 300 Gate Valves are designed for isolation service in medium and high-pressure piping systems where full flow capacity and minimal pressure loss are required. Featuring a full-bore design, flexible wedge gate, and OS&Y (Outside Screw & Yoke) construction, these valves provide reliable bidirectional sealing and long service life. The rising stem arrangement offers clear open/close indication, while the heavy-duty cast steel body ensures strength and durability under demanding operating conditions. Suitable for manual or automated operation, these valves are widely used in oil & gas, petrochemical plants, power generation facilities, water treatment systems, and various industrial process applications.
