During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height is relatively small. Sensitive action, good sealing performance; Open and close quickly. The overall structure: simple and compact, beautiful shape, low cost for throttling compared to regulating valve. Long service life and high reliability.
Application Scenario: The throttle stop valve is generally used on the pipelines where the flow resistance requirements are not strict and the regulatory flow requirements are not high. For example, a high-temperature and high-pressure working medium, toxic and harmful dangerous liquids, the
closure of closure must ensure long-term sealing, leakage and inaccurate regulating flow. Such as the application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry and other fields.

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.
RAYS single driving double ball valve is a special ball valve design, which combines two ball valves together, but is operated by only one drive device. This design is usually used in situations where two parallel pipelines need to be controlled or isolated at the same time. The design and application of single drive double ball valves need to consider specific process requirements and operating conditions to ensure its long-term stable operation and system safety.
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
