Flanged Valves
What are Flanged Valves?
Flanged valves are industrial valves that use flanged ends to connect directly to pipeline flanges, providing a secure and leak-resistant joint. They are widely used in high-pressure and high-temperature systems for industrial applications.
Asiad Steel Industries is a trusted manufacturer, supplier, and exporter of premium flanged valves under the Racer brand. Racer flanged valves are designed for durability, corrosion resistance, and precise flow control, making them ideal for industries such as oil & gas, petrochemical, water treatment, and power generation.
