Replies are encouraged – feel free to discuss! ------------------------------------------- Recently, the NPS20-CL1500 high-pressure four-eccentric butterfly valve, designed and manufactured by Jiangsu Shentong, has completed its assembly, testing, and various performance trials, and will soon be delivered to a large domestic enterprise for use. These high-pressure butterfly valves will be used in a large-scale coal chemical gasification plant, where they will serve to regulate flow and shut off flow in processes such as the syngas circulation loop. High-pressure butterfly valves feature a four-eccentric structure, which offers advantages such as lower operating torque, better sealing performance, and a longer service life compared to the traditional three-eccentric structure. The sealing pair adopts a metal hard-sealing structure and is treated through special processes, which enhances its wear and erosion resistance and enables effective extension of the valve’s service life. After rigorous performance tests, all performance parameters of this batch of valves met the design requirements. The valve features high load-bearing capacity and excellent control properties, achieving two-way \"zero leakage\" in terms of sealing performance, which is at the international leading level.
