1, metal butterfly valve structure simple, compact, small volume, convenient installation;
2, sealing structure is unique, between the butterfly plate and the valve seat adopts mechanical seal method, zero leakage two-way sealing requirements;
3, using different materials of metal valve seat can meet the requirements of different application conditions;
4, sealing surface using carbide surfacing materials, provide product sealing surface wear resistance, extend valve life cycle;
5, in the middle of the open and position, the butterfly plate and valve seat is not contact, friction small, butterfly valve operating torque is low;
6, the reasonable structure of the valve to make it applicable to - 200 ℃ ~ + 600 ℃ temperature range.
7, in the process of maintenance, do not need to remove the butterfly plate and the valve shaft, seat can overall replacement.
