FCT Cryogenic Gate Valve

FCT Cryogenic Gate Valve

FCT Cryogenic Gate Valve – Reliable Isolation in Ultra-Low Temperatures

FCT cryogenic gate valves are specifically designed for cryogenic applications ranging from -196°C upward, ensuring zero leakage and thermal integrity. Their extended bonnet design keeps the stem and packing area away from freezing temperatures, protecting the sealing system and allowing safe actuation.

These valves are ideal for liquefied natural gas (LNG), liquid oxygen, liquid nitrogen, and other low-temperature gases in storage tanks, pipelines, vaporization units, and transport systems.
