Product features of clip type rubber lined butterfly valve
1. The valve adopts double eccentric structure, which has the tighter and tighter sealing function and reliable sealing performance.
2. The sealing materials are made of stainless steel and acrylonitrile butadiene acrylonitrile rubber.
3. The rubber sealing ring can be located on the valve body or on the butterfly plate. It can be applied to different media for users to choose.
4. The butterfly plate adopts a frame structure, with high strength, large flow area and small flow resistance.
5. The whole baking paint can effectively prevent rust and can be used in different media as long as the sealing material of the sealing valve seat is changed.
6. The valve has the function of two-way sealing. It is not controlled by the flow direction of the medium and is not affected by the space position. It can be installed in any direction.
7. The rubber lined butterfly valve has unique structure, flexible operation, labor saving and convenience.
