RAYS has completed the manufacturing and delivery preparation of DN1200 | PN25 rising stem wedge gate valves for a gas pipeline project.
As large-diameter pipeline isolation equipment, these valves require careful control of structural strength, sealing reliability and operating stability throughout the manufacturing process.
The valves feature an rising stem wedge design with a reliable stem-to-wedge connection for stable torque transmission. Hardfaced sealing surfaces improve wear resistance and support long-term sealing performance. A two-stage low-emission packing system enhances stem sealing reliability and helps minimize leakage risks during operation.
During final assembly, key factors including stem movement, wedge guidance, seat sealing contact and valve position indication are carefully controlled to ensure reliable field installation and operation.
From structural design to manufacturing verification,
