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.
When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other
