The cryogenic valve, an advanced innovation in valve technology, is meticulously crafted for use in ethylene, liquefied natural gas, and a myriad of other chemical applications. This exceptional valve class is expertly categorized into two main types: the cryogenic floating ball valve and the cryogenic standing ball valve, each tailored for specific operational needs. The long-necked structure of this valve is typically not employed for environments where the temperature exceeds -50ºC, making it ideal for use in conditions where temperatures plummet below -50ºC. This design is meticulously engineered to safeguard the stuffing box by positioning it at a safe distance from extreme cold, ensuring optimal performance. To enhance sealing efficacy, cold insulation materials may be applied, preventing any loss of cold energy. Precisely designed for ethylene, liquefied natural gas, and other chemical apparatus, this valve is an indispensable component. Design and Manufacture Standards
