High performance three eccentric metallic sealing butterfly

SUFADA High Performance Triple Eccentric All metallic Sealing Butterfly Valve

Specific Property
?Sealing ring of body,disc is all metallic structure,not contain any graphite,asbestos,carton fiber ,won’t produce any pollution to medium.
?Triple eccentric structure can attain no-friction in theory,sealing force directly from torque provided by actuator fixed in stem.With the change of nominal diameter and nominal diameter and nominal pressure,cone angle between body and sealing ring will also change.Using min-radial eccentricity,min-torque, ensure sealing and no interference between sealing face,save driving energy,minish the resistance coefficient.
?Adopted stem is whole stem,more safety and credibility.
