FCT Bolted Bonnet Globe Valve

FCT Bolted Bonnet Globe Valve

FCT Bolted Bonnet Globe Valve – Rugged Construction for Critical Flow Regulation

FCT bolted bonnet globe valves are built with a robust body-bonnet connection that ensures long-term integrity under high-pressure and high-temperature service. The linear motion design provides accurate throttling and tight shut-off, while the bolted bonnet allows for easy access during maintenance.

These valves are ideal for oil & gas facilities, power plants, chemical processing units, and steam distribution networks, where precise flow control and serviceability are essential.
