When installing, leave the butterfly valve partly open. Make sure there is
enough distance between pipeline flanges to place the valve. Don’t add
sealing gaskets between the flange and the valve.
Insert bolts into flange and tighten opposing nuts sequentially. Make sure
that valve is aligned with the flange.
Fully open the valve. Make sure that the disc is centered and there is no
jam between the valve and the disc.
