The Lifting Plug Valve reduces the operating torque through hydraulic balancing technology and is equipped with hardened metal sealing surfaces, capable of withstanding temperatures up to 425℃. The unique lifting mechanism effectively prevents wear on the sealing surface during the opening and closing process. It features a fire safety design and complies with API 607 standards. The integral forged valve body structure allows for a pressure rating up to Class 2500. It is suitable for high-performance applications such as catalyst transportation and coal chemical industries involving solid particle media.

The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
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.
