产品概述: Product Overview of D71X Wafer Soft Seal Butterfly Valve :

The soft seal center-line wafer type butterfly valve developed by our company, double eccentric flange type butterfly valve has compact structure, easy 90 ° rotary switch, reliable seal and long service life. It is widely used in water plants, power plants, steel plants, papermaking, It is used for regulation and cut-off in the water supply and drainage of food and other systems .

特点: Features of D71X Wafer Soft Seal Butterfly Valve :

1. The valve adopts double eccentric structure, which has a tighter sealing function as it closes, and its sealing performance is reliable.

2. The sealing sub-material is made of stainless steel and nitrile oil-resistant rubber, which has a long service life.

3. The rubber seal can be located on the valve body or on the butterfly plate. It can be used for different characteristics of the medium for users to choose.

4. The butterfly board adopts a frame structure, which has high strength, large flow area and small flow resistance.

5, the overall baking paint, can effectively prevent rust and as long as the sealing valve seat sealing material is replaced, it can be used for different media.

6. The valve has a two-way sealing function. It is not controlled by the flow direction of the medium and is not affected by the space position during installation. It can be installed in any direction.

7. The valve is unique in structure, flexible in operation, labor-saving and convenient.
