Triple Eccentric Butterfly Valve - Composite Stainless Steel Sealing Ring, Zero Leakage Performance With Elastic Torque Seal For Optimal Flow Control

We are engaged in manufacturing and supplying excellent quality Triple Eccentric Butterfly Valve to our valuable clients. The first eccentric,shaft deviate from the centerline of sealing face.
The second eccentric,shaft deviated from the centerline of pipe and valve.
The third eccentric,the distinctive included angle between oblique taper angle of eccentric seat and centerline of pipe,thus making the seat completely disengaged from the sealing ring during the whole process of open and close.This structure not only uses cam effect,but also eliminates the possibility of abrasion and leakage.
The zero leakage of out triple eccentric butterfly valve is implemented by the composite stainless steel sealing ring mounted on the disc.
Zero leakage is implemented by the elastic sealing ring mounted on the disc.The elasticity of sealing ring(see fig.)is produced by its radial compression and flexibility.The contact surface between the sealing ring and seat is an oblique cone.The contact angle between them gives slight' wedge effect',making the sealing ring producing flexibility and radial compression.The even contact between the seat and sealing ring,and the closest cut off by the lowest torque.The elasticity produced by the torque makes the valve colsely cut off,regardless of the flow direction or pressure of medium
Elastic property of composite metal sealing ring to perform zero leakage.
Torque seal to ensure persistent two-way zero leakage.
