FCT Bolted Bonnet Gate Valve

FCT Bolted Bonnet Gate Valve

FCT Bolted Bonnet Gate Valve – Proven Isolation for Demanding Industries

FCT bolted bonnet gate valves are manufactured in accordance with API 600 and ASME B16.34, featuring a solid or flexible wedge, metal-to-metal seating, and a bolted body-bonnet connection. This configuration ensures structural integrity, especially in high-pressure and high-temperature environments.

The design allows for easy removal of the bonnet for internal inspection, seat replacement, or maintenance, making it a preferred choice in industries that require long valve life and field serviceability.
