Reliable Shut-off for Ultra-Low Temperatures
Oswal’s Cryogenic Gate Valves deliver safe, bubble-tight isolation in liquid gases and low-temperature media. The extended bonnet keeps stem packing above the vapor line, reducing icing and ensuring long packing life. Precision machining and material traceability make them the preferred choice for LNG terminals, hydrogen infrastructure, and process plants handling cryogens.
