Motorized Flange Type WCB Metal Seated Butterfly Valve

Motorized  Flange Type WCB Metal Seated Butterfly Valves are developed based on the mechanism of the butterfly valve and segment ball valve ,The special butterfly valve can be used at inlet of the water pump,piping network system,recovery stem,high water tank,sewage system and the back flow prevention to shut off or control the pipeline.

Benefits

1.Designed with bidirectional sealing structure,the installation of the moterized butterfly valve will not be restricted by the direction of the fluid.

2.Since the metal sealed butterfly valve is offered with self-sealing device,reliable sealing performance can be realized under the pressure from medium.

3.Powerful specific pressure of sealing can be obtained the valve is installed on the direction in opposite to that of the fluid.The pressure acts on the valve seat of the bidirectional rotary ball valve. The contact area of the point action is annular.

4.The motorized butterfly valve has a longer lifetime due to wear compensation.

5.The unique rotational structure ,as well as the sphere-conical sealing surface of the valve seat,makes for the cleaning function the solid particle will be crushed when the electric operated bidirectional rotary ball valve is opened or closed.The strong powerful shearing force can cut off the steelwire ,while the sealing surface is still keep good .

6.Large size type can be made ,max size up to DN3000
