BT320 High Performance U-Ring Triple Eccentric Butterfly Valve

BT320 is high performance U-Ring triple eccentric butterfly valve. The valve body is cast as a whole with a triple eccentric structure, and the valve seat utilizes the metal U-Ring structure. The special structure of the butterfly valve has made it form a series, and it is the real high performance triple eccentric core butterfly valve. The valve plate and valve seat is sealed by mechanical force, rather than by the pressure difference of the medium. The optional valve seat can further improve the sealing performance of the valve. The series of valves are widely used in pulp paper, chemical, petrochemical and oil refining and other industries.

Performance Characteristics   

1, The hard sealing butterfly valve utilizes t triple eccentric hard sealing structure. The U-Ring valve seat and the butterfly plate are sealed tighter as they are closed tighter.
2, The sealing ring is made of Inconel alloy, with dual advantages of metal seal and the elastic seal. It has excellent sealing performance both in the low and high temperature. And it is corrosion resistant, and has long service life and other characteristics.
3, The sealing surface of the butterfly plate is welded with cobalt base hard alloy. It is wear resistant, and has long service life.
4,Large scale lattice structure, high strength, large flow area, small flow resistance.
5,The unique totally-metal seal ensures that it still has a long time good sealing performance in harsh environment.
6,The valve plate and valve seat is sealed by mechanical force, rather than by the pressure difference of the medium.
7,The regulating valve has lower cost in low pressure.

Product Advantage   

1, Compared with that of BT310, the sealing ring of BT320 is Inconel pure metal ring, so the wear resistance ability is better than that of the laminated seal ring consisted of stainless steel plate and flexible graphite sheet.
2, T320 sealing ring is totally metal ring. The valve plate presses to sealing ring, so that the sealing ring hoop in the valve plate to seal. Therefore it has a certain shearing function, suitable for some slurry and fiber media occasions.
