Product Description

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.
