en.Wedoany.com Reported - China Jiangsu Shengtai Valve Co., Ltd.'s independently developed new "triple-eccentric" hard-seal butterfly valve achieved mass production in the first half of 2026 and has now fully entered the production and delivery phase. This product is expected to bring nearly 30 million yuan in new orders for the company in 2026, primarily serving high-end valve application fields such as petrochemicals, offshore platforms, and industrial pipeline networks.
Jiangsu Shengtai Valve Co., Ltd., located in Tinghu District, Yancheng City, Jiangsu Province, is a high-tech enterprise integrating R&D, design, manufacturing, and sales of industrial valves. The company's product range includes gate valves, globe valves, check valves, ball valves, butterfly valves, and other categories, widely used in industries such as petroleum, chemicals, natural gas, power generation, and metallurgy. The new "triple-eccentric" hard-seal butterfly valve, now in mass production, is the result of a collaborative effort between Shengtai Valve's R&D team and the School of Mechanical Engineering at Yancheng Institute of Technology in the first half of 2026. This product breaks through the technical limitations of traditional soft-seal butterfly valves in its structural design.
According to Zhou Jianrong, Director of the Production Center at Shengtai Valve, the core technical advantage of the new "triple-eccentric" hard-seal butterfly valve lies in its unique sealing structure design. Compared to traditional soft-seal butterfly valves, this product adopts a metal-to-metal hard-seal structure and incorporates the triple-eccentric geometric principle in the sealing pair design. This allows the sealing pairs to quickly disengage during valve opening and closing, significantly reducing friction and wear on the sealing surfaces. Additionally, in the event of minor leakage, the sealing effect can be maintained by increasing external torque, greatly extending the service life compared to traditional soft-seal butterfly valves. With advantages such as high durability, precise sealing, and excellent stability, this product has opened new growth opportunities in the high-end valve market.
In terms of application areas, the new "triple-eccentric" hard-seal butterfly valve is primarily targeted at industrial scenarios with high demands on sealing performance and service life, such as petrochemicals, offshore platforms, and industrial pipeline networks. According to the company, Shengtai Valve is currently working intensively to fulfill petrochemical orders from regions like Xinjiang.
The successful development and mass production of this new butterfly valve represent a significant achievement for Shengtai Valve in deepening industry-university-research collaboration and advancing product upgrades toward high-end directions. Through collaborative innovation with university research capabilities, the company has achieved multiple technical breakthroughs in new product structural design, material selection, and manufacturing processes. The market launch of this product will further enrich Shengtai Valve's product line in the high-end valve sector and enhance the company's competitiveness in niche markets such as petrochemicals and marine engineering.
