Grinnell Series 8000
Resilient Seated Butterfly Valves, 2" to 36"

Wafer and Lug style resilient seated butterfly valves with
cartridge seat design.

FEATURES AND BENEFITS
• Suitable for high pressure and full
vacuum service due to the use of
a cartridge seat design.
• Triple function cartridge seat isolates
the body and stem from the media,
provides positive drop-tight shut-off
of line media at full rated pressure
and provides a flange seal, eliminating
the need for flange gaskets.
• Full rated unidirectional dead-end
service is achieved by utilizing a unique
patented lip in the lug body.
• Strong disc-to-stem connection and
elimination of exposed pins or bolts
is achieved through the use of a
rectangular drive.
• Ability to install the valve with the disc
in the closed position eliminates the
risk of damage to the valve during
installation.
• Maximum flow and rangeabililty
is achieved with the use of a
streamlined disc.
• Blowout-proof stems are standard.
• Longer seat life with low operating
torques is ensured by utilizing upper
and lower stem bearings.
• Need for costly brackets is eliminated
due to the ability to direct mount
actuation onto the valve top-plate.
