These valves are used in one of the world’s largest propane dehydrogenation plants, with an annual production capacity of 900,000 tons; they are installed at the location where exhaust gases are directed toward the waste heat boiler/chimney, and represent a new breakthrough in the localization of key control valves in this application area. This valve is large in size, operates at high temperatures, and requires high precision in manufacturing. Through joint development and close supervision by Nuway Suzhou’s team and the Italian technical team, no rework was needed throughout the production process; it passed all tests related to strength, sealing performance, and operational characteristics on the first attempt. It achieved zero leakage in both normal temperature conditions and high-temperature gas sealing tests at 465°C. This valve was produced during the peak of the COVID-19 pandemic. In an environment characterized by low resumption rates and shortages of related components in the global valve industry, Neway Valves overcame numerous challenges and completed this difficult task of domestic production in a short period of time, thereby ensuring the smooth progress of the project. The successful delivery of this valve not only demonstrates Neway Valves’ strong and reliable R&D capabilities, marking another significant breakthrough for the company in the field of high-end control valves, but it also boosts the confidence of domestic users and design institutes to choose Neway Valves for projects aimed at local production of high-end valves.
