Electric Ventilation Butterfly Valve can be installed at multiple stations without the influence of medium flow direction.

There are no connecting rods and bolts in the electric ventilation butterfly valve. It works reliably and has a long service life. The electric ventilation butterfly valve is designed and manufactured by a new structure of welding between the middle plate and the short structure steel plate. It has compact structure, light weight, easy installation, small flow resistance, large flow capacity, avoiding the influence of high temperature expansion and easy operation.
Electric Ventilation Butterfly Valve
Electric ventilation butterfly valve is a kind of non-hermetic butterfly valve. It is widely used in pipes with temperature of medium less than 300 C and nominal pressure of 0.1Mpa in the production of building materials, metallurgy, mining and electric power. It is used to connect, open and close or regulate the medium volume. The stem and disc of the electric ventilation butterfly valve should be absolutely coaxial. When the pressure difference is large, the flow in both directions can be guaranteed. The full-open inlet passage area is large, and the full-close time is completed. The valve body and disc of the electric ventilation butterfly valve should be sealed at the valve shaft without leakage. Valves and stem must not allow any packing.

The valve stem of electric ventilation butterfly valve is connected by square axle or key on the butterfly plate. It has large overflow area, large compression area, good compression resistance, reliable opening and closing, and bidirectional sealing function. Installation is not limited by the direction of medium flow, nor by the direction of space position, can be installed in the pipeline. The electric ventilation butterfly valve is driven by the valve shaft to rotate the disc valve plate 90 degrees. Rubber seals are mounted at will. The valve is driven by the valve shaft, and the valve plate is turned 98 degrees. The sealing of the valve body is easy to maintain and can be repaired online.
