Cryogenic Globe Valves are specially designed to handle low temperatures and cryogenic conditions. Constructed from durable materials such as stainless steel, carbon steel, and cast steel, these valves are equipped with an extended bonnet to ensure that the stem packing remains at a safe distance from the cryogenic fluid. The length of the bonnet varies based on the specific application and user requirements. Cryogenic globe valves are ideal for use in gas/terminal production plants, ethylene plants, and LNG (liquefied natural gas) applications. These valves are specifically designed to throttle cryogenic fluids with temperatures as low as -196°C, offering reliable performance in extremely cold environments.
