DN1800 Electric bi-directional Sealing Butterfly Valve with extended stem 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.
Benefits
1.Designed with bidirectional sealing structure,the installation of the bidirectional sealing butterfly valve will not be restricted by the direction of the medium.
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.The electrical bidirectional sealing meteal seated butterfly valve has a longer lifetime ?due to wear compensation.
4.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.
5.The length of valve stem can be customized
6.The valve can be operated underground .
