- Note:
- Generally bypass valve is necessary
in pipeline. If you install "Ported Disc
Butterfly Valve", you have no need to
install bypass valve and bypass line.
Long holes on "Ported Disc" are substitute
for bypass valve and we can fill water
by use them. "Ported Disc Butterfly Valve"
is equal to "Disc-in-Disc Butterfly Valve".
