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 Non-Rising Stem Gate Valve is also called the rotating stem gate valve. Stem and nut are arranged on the gate plate, handwheel rotation drive valve stem rotate to lift the gate, usually there is a trapezoidal thread at the bottom of the valve stem and the rotation movement is turned into a linear motion through the limit slot between the valve stem and the gate body and the gate body and the gate, that is, the operation torque is turned into operation thrust. When the valve is turned on, when the height of the gate is equal to the diameter of the valve 1: 1: 1, the channel of the fluid is completely unblocked, but at the run, this position cannot be monitored. In actual use, the vertex of the valve stem is used as a sign, that is, the position that is unmoved as its full opening position. The non-rising stem gate valve has the design characteristics of the ordinary wedge-type gate valve. The valve body has a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
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.
