Double eccentric Butterfly valve is widely used in water supply and drainage systems such as waterworks, power plants, steel mills, papermaking, chemical, catering and so on. Soft seal in the line of the folder-type butterfly valve, double eccentric flange butterfly valve compact, 90 ° rotary switch easy, reliable, long service life.
Features:

1, The valve with double eccentric structure, with the more close the tightening of the sealing function, sealing performance and reliable.

2, Sealed by the use of stainless steel and nitrile rubber resistant rubber pairing, long service life.

3, Rubber seals can be located in the valve body, can also be located on the butterfly board, applicable to different characteristics of the media for the user to choose.

4, Butterfly board with frame structure, high strength, over flow area, flow resistance is small.

5, The overall paint, can effectively prevent corrosion and as long as the replacement seal seat sealing material, can be used in different media.

6, The valve has a two-way sealing function, the installation from the media flow control, nor the impact of space position can be installed in any direction. 7, the valve structure is unique, flexible operation, effort and convenience.
