● Frictionless Switching: The unique design prevents friction against the valve seat, reducing wear compared to traditional valves.
● Single Seat Design: This design ensures no leakage downstream and prevents pressure build-up inside the valve.
● Self-Cleaning: The media flows 360 degrees around the seal when the valve core moves away from the seat, cleaning off any debris.
● Low Torque Required: Without friction on the sealing surface, the valve turns easily.
● Durable Hard Seal: The valve core's sealing surface is reinforced with hard alloy, making it reliable even in harsh conditions.
● Eccentric Design: This feature combines the best aspects of various valves, handling extreme conditions like high and low temperatures, frequent operation, and bidirectional shutoff more effectively.
● Full Bore Design: The design ensures an open, unobstructed flow path without any dead zones or build-up, eliminating the need for pressure relief.

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 Double Eccentric High-Performance Butterfly Valve is a new type of butterfly valve designed based on absorbing the advantages of several different structural butterfly valves. The sealing surface of the valve plate of this valve is a - spherical arc surface. The sealing mechanism achieves a true dynamic seal through system pressure, thus having reliable sealing performance and durability. It has a small volume, light weight, wide manufacturing range, and is easy to maintain and repair. Due to the design of the double eccentric butterfly plate, combined with a single piece of flexible lip-shaped sealing seat, it is suitable for valves in situations requiring reliable sealing and good regulating characteristics. It can be used for quick shut-off or regulating flow.
RAYS Side Entry Floating Ball Valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute Standard API 608&API 6D British standard BS 5351 and generally conform to American Society of Mechanical engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims.
