OverviewThe DJ11F low-temperature internal thread globe valve is a special valve designed specifically for ultra-low temperature conditions. It drives the valve disc vertically up and down along the centerline of the valve seat through the valve stem, achieving reliable opening and closing and flow regulation of the pipeline. The core of its design lies in the use of low-temperature materials and deep cryogenic treatment throughout the valve, ensuring that key components such as the valve body, valve cover, and valve disc maintain good mechanical performance in deep cryogenic environments and prevent low-temperature embrittlement. The sealing surface of the valve seat usually adopts rigid sealing or soft sealing structures with excellent low-temperature performance such as polytetrafluoroethylene. Combined with an elongated valve cover design, a "cold box" is formed at the neck of the valve cover away from low-temperature fluids, effectively preventing packing freezing, valve stem jamming, and reducing external heat transfer. The valve adopts internal thread connection and is directly screwed and fixed to the pipeline system through threads, with a compact structure. Valves rely on manual devices (such as handwheels) to drive the valve stem, converting rotational force into linear motion of the valve disc, achieving smooth and reliable opening and closing control. This valve is designed specifically for low-temperature transportation and storage systems in industries such as liquefied natural gas, liquid oxygen, liquid nitrogen, liquid argon, and liquid carbon dioxide. It is particularly suitable for various low-temperature medium operating conditions that require strict sealing and reliable operation within the range of -40 ℃ to -196 ℃.DJ11F Cryogenic Internal Thread Globe Valve Product Drawing
