Triple offset function:
Offset 1E:
The center of rotation is offset from the thigtness surface to allow a total contact around the entire seal.
Offset 2E:
The center of rotation of the disc is offset from the pipe centerline to allow a cleaning opening valve.
Offset 3E:
The third offset issue from the seal cone tilting cancel jamming and friction and allow complete tightness without seal deformation (solid seal).
Tightness:
Bi-directional tightness
Closing without jamming and friction
No deformation on the seal
