Small valve has three patents
At the third China (Wenzhou) Pump and Valve Pipeline Exhibition, held at the Wenzhou Convention and Exhibition Center, a new valve from Wenzhou Dayang Valve Co., Ltd. made a strong impression. Despite being just two months old, the company's booth attracted considerable attention with its unassuming yet innovative design. The standout product was a three-piece forged flange valve, featuring advanced technology that caught the eye of many industry professionals.
This patented valve is a one-piece, integral forged flange valve, manufactured using the latest die forging process. It integrates the valve body and flange into a single unit, making it ideal for high-temperature, high-pressure, and corrosive environments—especially in the petrochemical industry. Applications include hydrocracking systems, desulfurization equipment, and pipelines handling flammable or explosive materials.
Unlike traditional welded flange valves, this design eliminates welding-related risks, enhances structural strength, and improves corrosion resistance. Its elegant appearance combines aesthetics with functionality, offering a safer and more reliable alternative to conventional valves. The product has already gained recognition, winning prestigious awards such as the "Eureka World Invention Gold Award" and the "China International Patent Technology and Product Fair Gold Award."
Wenzhou Dayang Valve Co., Ltd. was officially launched on July 31 this year. It was established through a joint venture between Dalian Dayang Valve R&D Co., Ltd., which specializes in high-tech valve development, and Zhejiang Chenjian Forging Co., Ltd. Together, they focus on producing and selling high- and medium-pressure valve series products, including patented technologies and integral flange valve components. With its innovative approach and commitment to quality, the company is quickly making its mark in the global valve industry.
