Product Description

Double flange Triple offset butterfly valve description
This kind of butterfly valve adopt three-dimensional eccentric principle to design, So it makes the movement track on facing space reach
to idealization, and there are no attrition and no intervene between
hermetical components, furthermore, the hermetical material has been
selected reasonably, thereby it ensure hermetic, 10.antisepsis,wear
able capability of valve. 

Product features of double flange Triple offset butterfly valve
1.  Tiny moment for starting, flexible and convenient, save labor and energy
2. Three-dimensional eccentric configuration forces disc close tighter
and tighter, and reach to reliable hermetic capability and with no leakage
3. It has characteristic of high temperature resistant, high pressure
resistant, antisepsis, wearable, long service life etc
2.
