RAYS' rising stem ball valve is designed to operate without friction between the ball and the seat during opening and to achieve zero leakage when closed. This makes it well-suited for demanding conditions. The valve is made entirely of metal and is fire-resistant, capable of functioning in extreme temperatures ranging from -196°C (320.8°F) to 538°C (1000.4°F). It can handle media with particulates like sand and short fibers, and meets NACE standards for corrosion resistance, ensuring it can resist sulfide stress cracking in harsh environments. The valve also features a self-cleaning mechanism. When the ball is tilted away from the seat, the fluid flows 360° around the ball's sealing surface, effectively removing any debris. This prevents damage from high-speed fluid flows and keeps the sealing area clean. The rising stem ball valve is ideal for various applications including exhaust, fluid transfer, pipeline isolation, bypass, product segmentation, and emergency shutdowns, particularly where high switching frequencies and zero leakage in high temperatures are required.
The hard-sealed butterfly valve is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.
