API Double-eccentric Butterfly Valve Double Offset Double offset
Foowell Butterfly valve is a kind of vale that takes a disc as
closing part (butterfly board) which rotates around the valve axis
to achieve opening and closing. The valve is mainly for cut-off and
throttling on pipeline.During valve opening or closing, the butterfly plate sealing face
will be deviated gradually from and pressed into gradually the
valve seat sealing face, thus reducing the mechanical abrasion and
damage between the butterfly plate and the valve seat during
opening or closing.
