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.
This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
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.
