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.
The Axial Flow Control Valve is a high-performance control valve featuring an advanced structural design. Its straight-through streamlined flow path allows the throttling element to align with the direction of media flow, reducing energy loss and increasing flow capacity by approximately 20%–50%. With a low flow resistance coefficient, robust structure, low maintenance requirements, and high performance, the valve is widely used for the regulation and control of natural gas, crude oil, refined oil, and other non-corrosive gases and liquids.
Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
