Triple Eccentric Butterfly Valve

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 bet
