Characteristics:
Adopt to triple-eccentric structure, disc and seal can float and be regulated in axial and radial direction, so that the disc and seal in closure are always in the best linear contact seal. With the appropriate sealing material used, so the sealability, corrosion resistance, high-temperature resistance and abrasion resistance can be granted. This type can be widely used in metallurgy, electric utility industry, chemical industry, air, coal gas, combustible gas, water supply and drainage and pipelines with other corrosive fluid.
