Gate Valve Flanged End
What is a Gate Valve Flanged End?
Gate Valve Flanged End (FE) is a heavy-duty, bolted flange connection type valve designed to start or stop the flow of liquids and gases in large pipelines. The flanged ends ensure a strong, leak-proof joint suitable for high-pressure and high-temperature applications.
Asiad Steel Industries manufactures and exports high-performance Gate Valve Flanged End (FE) under the Racer brand. Built to international standards, these valves are widely used in industries such as oil & gas, power, water treatment, and petrochemical plants.
