Dual Eccentric Butterfly Valve
The dual eccentric valve seat design achieves more ideal sealing and pressure-resistant performance when the valve disc are fully closed, and reduce the torque effectively and increase the valve seat’s service life.
When the valve disc are open, the valve seat will be separated from the disc seat more quickly; when they are fully open, the valve seat will be completely separated from the disc seat, avoiding permanent deformation of the valve seat near two sides of the valve shaft, which will affect the valve’s sealing performance.
