The jacketed structure facilitates online maintenance. Without the need to dismantle the pipeline, the valve seat or sealing parts can be quickly replaced, significantly reducing maintenance costs. The fixed ball design reduces valve ball wear, and in combination with the low-torque valve stem bearing system, the operation is lightweight and has a long lifespan. The ultra-low temperature adaptability is verified through material optimization and structural simulation, avoiding cold flow phenomena; the bidirectional metal sealing structure maintains sealing integrity under high pressure differences. The overall design takes into account both lightweight and high strength, supporting electric, pneumatic or manual drive, meeting the requirements of automated control, and suitable for deep cold environments with high safety requirements.

The C-type wear-resistant ball valve is a valve designed specifically for harsh working conditions, characterized by its eccentric ball setting and "C" - shaped channel. This design cleverly utilizes the translational characteristics of the sphere during rotation, achieving a "wedging" effect with the valve seat, thereby significantly improving the sealing performance. In addition, its ingenious upper and lower support axis positioning structure not only ensures the stability of the sphere, but also avoids tilting, allowing the medium thrust to be evenly dispersed, thereby extending its service life. This design not only optimizes the sealing performance, but also reduces the opening and closing torque and improves the opening and closing efficiency. Widely used in industries such as coal chemical, petrochemical, offshore platforms, LNG, etc.
The structure adopts a short pattern, the valve gate is light in weight, and the pipe support frame can be saved. Diversified Drive Modes: Electric, gearbox, hydraulic and pneumaticcan be selected at will. High performance sealing combination packing: The combined packing sealing system isadopted to greatly improve its sealing performance.
RAYS PDS Ball Valve is designed for extreme conditions characterized by high temperatures, high pressures, and abrasive media. Manufactured from premium alloy steel and enhanced with advanced hardening techniques, it offers exceptional wear resistance for both the ball and the seat. The hard seal design ensures superior sealing performance in harsh environments. Additionally, the valve features a robust construction and is easy to operate and maintain, significantly reducing maintenance costs. It is an ideal choice for heavy industries such as petrochemicals, power generation, and mining.
