VEB series eccentric butterfly valve (referred to as high-performance butterfly valve), the valve plate and the sealing ring adopt a unique eccentric structure, featuring compact structure, good cutting performance and long service life, and both functions of adjustment and cutting. Widely used in metallurgy, chemical, electric power, textile, food, medicine, paper and other industrial parts and municipal engineering, water plants. The pipeline cuts off the pressure of the tap water, natural gas, water vapor and other media.
The high-performance adjustment cut-off type can be used as both a regulating valve and a shut-off valve.
The two-way seal type is different from the general single seal, and can be reliably sealed even if the medium is reversed or a hammer is generated.
The seal ring has a novel design and adopts the internationally advanced technology: the PTFE seal adopts the “lip-tooth” type self-sealing structure; the hard seal adopts the “U”” elastic seal. The sealing structure has a long service life and is reliable.
