Cryogenic gate valves are designed for controlling the flow of extremely low-temperature fluids, typically ranging from -40℃ to -196℃. These valves are essential in industries handling cryogenic substances like liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid oxygen (LOX), and liquid nitrogen (LN2), as well as in storage tanks, pipelines, and transportation systems for these volatile materials.
Cryogenic gate valves are primarily used for full shut-off or isolation of flow, rather than throttling. They feature a traveling wedge that moves perpendicular to the flow direction, ensuring minimal pressure drop when fully open and a tight seal when closed. This design prevents leakage, even in high-pressure, low-temperature environments, where the media is highly flammable and explosive.
