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.
