Pneumatic buttefly valve

Highlight: Pneumatic buttefly valve

Product introduction:

The triple-eccentric multi-layer metal hard-sealed butterfly valve series represents a new generation of industrial valves that

integrate long service life, zero leakage, and high energy efficiency, symbolizing the technological innovation direction in the

field of fluid control. These products are meticulously designed based on the three-dimensional eccentricity principle. By

ingeniously setting the triple eccentric distances among the valve seat centerline, butterfly disc rotation centerline, and

sealing surface centerline, they effectively avoid direct friction between the butterfly disc and valve seat during opening/

closing, significantly reducing wear. This enables the valves to maintain stable performance under frequent operation

conditions, with a service life 3 to 5 times longer than that of traditional butterfly valves. The core sealing structure adopts a

multi-layer design combining hard and soft materials. The inner layer is composed of high-strength alloy metal rings, featuring

excellent resistance to high temperature, high pressure, and corrosion to meet the demands of harsh working conditions such

as metallurgical steelmaking and petroleum cracking. The outer layer is wrapped with flexible sealing materials, which work in

tandem with the metal rings through pre-tightening force to achieve dual sealing protection, effectively eliminating fluid leakage

and reducing energy loss and safety hazards.

Product features:

1. The butterfly disc features a hard-soft multi-layer seal, combining the advantages of both hard and soft sealing. It delivers excellent sealing performance under both low-temperature and high-temperature conditions.
2. With a triple-eccentric structure, there is minimal friction between the valve seat and the butterfly disc. The sealing tightens as the valve closes, ensuring zero leakage.
3. It has a small opening/closing torque, flexible operation, energy efficiency, and a long service life.
4. Resistant to high temperatures, high pressures, and corrosion, it offers a wide range of applications.
5. The new-generation triple-eccentric servo-sealed butterfly valve integrates the benefits of the triple-eccentric sealing structure and soft sealing. It provides reliable sealing, a broad application scope, and an extended service life.
