Gate Valves Class 900
Gate Valves with Class 900 and 1500 pressure ratings are designed for high-pressure applications, offering excellent durability, sealing performance, and flow isolation. These valves are commonly used in industries such as oil and gas, chemical processing, power generation, and water treatment, where safety, performance, and reliability are critical.

The flanged end connection ensures a robust, leak-tight connection that is easy to install, maintain, and replace in pipelines. Gate valves are generally used for full open or full closed operations, offering low resistance to fluid flow when fully open. The gate valve operates by lifting a wedge or disc, allowing fluids to pass with minimal pressure loss.
Gate Valves Class 900 & 1500 with flanged ends provide a reliable solution for high-pressure and high-temperature applications, ensuring smooth operations, safety, and long service life in critical service environments.
