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. The action is sensitive and the sealing performance is good; The overall structure, simple and compact, beautiful shape. Long
service life and high reliability.
Application Scenario: The deeper valve is generally used on the pipelines that are not strict with the flow resistance on the pipeline, that is, the place where the pressure loss is not large. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require
closure to ensure long-term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. 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' Double Disc Gate Valve-Ethylene is manufactured using high-strength, high-temperature resistant materials, specifically designed for handling cracked gases in the petrochemical industry. This valve features exceptional sealing capabilities and low maintenance requirements, effectively handling high temperatures and corrosive media. Its unique slab gate design ensures smooth fluid flow without any obstruction, thereby reducing pressure loss and enhancing system efficiency. Additionally, the valve is equipped with an automatic self-cleaning feature that removes deposits during operation, ensuring reliability and stability over long-term use. Ideal for both new projects and upgrades of existing systems, the RAYS Double Disc Slab Gate Valve-Ethylene is a perfect choice for enhancing productivity and safety.
The axial-flow check valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
