Application:
Bi-direction butterfly valve absorbs, digests foreign technology, adopts triple eccentric multiple metal sealing, it used in industrial pipeline for media temperature ≤**0°Cof metallurgy, electric power, petrochemical, air, gas, flammable gases, water supply and drainage as the best device of medium adjustment and cutoff.
Main features:
Duplex butterfly valve adopts multiple triple eccentric metallic
sealing structure, it's contains all the advantages of common
multiple triple eccentric metallic sealing butterfly, owing to this
design reasonable reduced radial eccentric value, valve stem bared
less torque in closing state, in stable static equilibrium,
meanwhile, butterfly disc sealing ring uses high-quality carbon
steel and high-toughness stainless steel composites multiple
structure, this is not only just keep best seal closing with the
valve seat, but also have favorable self-compensatory function,
especially under the condition of large differential temperature,
it can eliminate the impacts of sealing performance from the
Structure deformation.This butterfly valve whether in positive or
reverse under pressure,it can reach zero leakage under the full
differential pressure.
