Metso Butterfly Valve B2B08AABD 8in Class 300

Rated 0 out of 5
(be the first to review)


Series B2 ultra heavy-duty butterfly valves are
designed to handle high-cycle control services
such as switching on continuous digesters and
liquor and steam circulation on batch digesters.
On digester-switching service, the valves must
cycle every 90 seconds or 350,000 times a year
while handling hot liquor, scale buildup, and
sawdust at high flow rates. Because it was
designed for services where other valves have
failed, Series B2 control valves include many
features as standard that would be extra or even
unavailable on other valves.
