1. High reliability of strength and rigidity.
2. Adopt double eccentric construction, small friction of seat and torque during opening or closing..
3. The disc is truss framed with plates, lower flow resistance..
4. Good seal function, 0 leakage.
5. The rubber sealing ring could be replaced on pipeline without removing the valve.(DN>=700)
6. The axle bearings are self-lubricated type, oil is not needed, frication drag is small during operation.
