This product can be used as the shut-off valve, control valve and check valve of the pipeline system. Intact manual control equipment, electric or pneumatic transmission equipment can meet the specific conditions of different working conditions. It meets the most stringent quality requirements and can be used for a very long time. Especially in metallurgy, steel and ship industry, it is very famous. The electric butterfly valve is suitable for the occasion of demand flow conditioning. Since the pressure loss of butterfly valve in the pipeline is relatively large, about three times that of gate valve, when selecting butterfly valve, the impact of pressure loss on the pipeline system should be fully considered, and the consolidation of butterfly plate receiving pipeline medium pressure when closing should also be considered. In addition, the constraints of operating temperature accepted by elastic seat data at high temperature must also be considered.

The existing advanced butterfly valve is a tri eccentric metal hard seal butterfly valve. The valve body and valve seat are integral components, and the sealing surface layer of the valve seat is welded with heat-resistant and corrosion resistant alloy materials. The multi-layer soft laminated seal ring is fixed on the valve plate. Compared with the traditional butterfly valve, this butterfly valve has the advantages of high temperature resistance, easy operation, no friction when opening and closing, and compensation sealing with the torque of the transmission mechanism when closing, which improves the sealing performance of the butterfly valve and extends its service life.
