Time is the best test. In 1997, Guangdong Yunliu Lianfa Company purchased a triple-eccentric metal hard-seal butterfly valve from Xuanda Industrial Group for the "250,000-ton pyrite-to-acid project". After 27 years of operation, it still maintains a stable working condition.

On October 16, 2025, the second working meeting of the drafting group for the national standard "Design Specification for Sulfuric Acid Production Process from Smelting Flue Gas" was held at Xuanda Industrial Group. The revision work was jointly carried out by China ENFI Engineering Technology Co., Ltd., Shanghai Aogli Environmental Engineering Co., Ltd., and other relevant units. This revision aims to adapt to industry development, improve the industry's technical level, and promote the standard to better play a guiding role in energy conservation, emission reduction, carbon peaking, and carbon neutrality.

Recently, the second session of the 8th Member Representative Conference of the Valve Branch of the China General Machinery Industry Association was successfully held. Ye Jixuan, Chairman of Xuanda Industrial Group, attended the meeting as Vice Chairman of the China Valve Association. He joined Huang Li, President of the China General Machinery Industry Association; Sui Yongbin, Honorary President and Chief Supervisor; Zhang Zonglie, Vice President; industry leaders, experts, scholars, and corporate representatives to discuss the industry's development plans and draw a blueprint for transformation and upgrading.

On July 18, Xuanda Industrial Group Chairman Ye Jixuan and President Ye Qunzhe visited Yunnan Institute of Chemical Technology for exchanges and inspections. The two sides reached an important strategic consensus on cooperation in the field of phosphorus chemical industry.

Recently, five innovative valve products independently developed by Xuanda Industrial Group - "U-type wear-resistant gate valve", "high-temperature bidirectional metal-sealed butterfly valve", "high-performance anti-flying stem fixed ball valve", "acid-resistant lined angle bell valve" and "water injection and venting system ball valve" have been successfully identified as Zhejiang Province's new industrial products in 2024 after strict review by provincial expert judges. This achievement marks another major breakthrough for Xuanda Group in the field of valve technology and sets a new benchmark for the industry.

Xuanda Valve, a leading manufacturer of industrial valves, proudly participated in the 12th China International Fluid Machinery Exhibition (CIFM 2024), held from 25th~27th November at the International Convention and Exhibition Center in Shanghai. The exhibition attracted global industry leaders, professionals, and technology experts from the fluid machinery sector to explore the latest innovations in valve and fluid control technologies.
