DN2200 Spherical Disc High Performance Butterfly Valve

DN2200 Spherical Disc High Performance Butterfly Valve  is 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.

BENIFITS

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

2.Since the metal seated bi-directional sealing 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 spherical disc valve. The contact area of the point action is annular.

4.The spherical disc butterfly valve has long service life 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.

6. Really metal seated design ,especially suitable for non-clean industrial waters .
