The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
Developed with: principles of standardization, universality, modularity, and interchangeability. Valves of different sizes maximize part
interchangeability, universality, and ease of maintenance. This ensures low operational costs. They can be made into special structures such as:
the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve.

It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
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.
Mainly suitable for cutting off or connecting pipeline media in various systems of thermal power plants. Applicable media: non corrosive media such as water and steam. The characteristics of forged steel valves compared to other valve products are high temperature and high pressure, unique self sealing design, and the higher the pressure, the more reliable the seal. Due to its unique performance, technical characteristics, and working conditions, the product has also developed unique features that cannot be replaced by other products.
