The Cryogenic Gate Valve is a type of equipment used for full opening and full closing operations. The opening and closing element of the low-temperature gate valve is a gate plate. The movement direction of the gate plate is perpendicular to the flow direction of the fluid. The gate valve can only be operated in full opening and full closing positions, and cannot be used for regulation or throttling. The gate plate has two sealing surfaces. The most commonly used type of gate valve has two sealing surfaces forming a wedge shape, and the wedge angle varies with the parameters.
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.
