Electric Operated Soft Sealing Butterfly Valve
The electric operated soft seal butterfly valve uses the electric actuator as the driving device of the valve, and the rotating valve stem drives the butterfly plate to rotate within the range of 0-90 ° to complete the opening and closing of the valve. The electric actuator structure is generally provided with a manual operating device. In case of power failure, manual and electric switching can be carried out to ensure the operation of the valve in an emergency state. The valve structure is a flange type double eccentric soft sealing structure, which can be used as the shut-off valve, control valve and check valve of the pipeline system. Electric or other corresponding operation modes are recommended for large diameter butterfly valves with diameters exceeding DN600.

Tilted Plate Rubber Sealed Butterfly Valve
The tilted plate soft seal butterfly valve is a product developed by our company for foreign customers and continuously optimized. It can be widely used in water supply and drainage, petroleum, chemical industry, electric power, municipal construction and other pipelines in domestic and foreign for cutting off or regulating the medium flow. The product has undergone a long-term practical test, and its performance has been in the leading level at home and abroad.

Flanged / Wafer Type Triple Eccentric Butterfly Valve for sour and alkaline medium
Triple eccentric butterfly valve, the valve stem shaft center deviates from the center of the plate and the body center, and the seat rotation axis has an angle from the axis of the body channel. When the valve is fully open, the plate sealing surface will completely deviate from the seat sealing surface. When the plate opens from 0 to 90 degrees, the plate sealing surface gradually leaves the seat sealing surface, and the valve opens. When the plate opens from 90 to 0 degrees, the plate sealing surface gradually approaches the seat sealing surface, and then press and the valve closes.

Soft Seal Bi-direction Butterfly Valve
Butterfly valve is one of obstructing valves to connect or block the medium in the pipeline, it can also adjust the flow of medium in the pipeline. Its closing element (disc) is in the shape of disc that can revolve the axis itself to block the medium in the pipeline or adjust the flow.

Metal Seated Bi-directional Butterfly Valve
Metal seated bi-direction butterfly valve adopts double eccentric structure, the structure of double eccentricity greatly eliminates the unnecessary excessive extrusion and scraping phenomenon of the plate and the valve seat. The large reduction of scraping makes the butterfly valve with the metal valve seat improve the performance.

Central Line Wafer Butterfly Valve
Central line wafer butterfly valves are used cut-off or connect the medium in the line. The steering center of the butterfly plate is on the center line of the valve body and the butterfly plate seal area. When the valve is closed, the circumscribed sealing surface of the butterfly plate will squeeze out the synthetic rubber valve seat and produce elastic deformation on the valve to ensure the sealing of the butterfly valve.
