provides rapid shut
off while keeping the
metering ow presetting.
Encapsulated ball stem
design has virtually no
dead space to minimize
system contamination.
GENERALFEATURES
The Shut-off Metering Ball Valve Series provides the highest
degree of precision metering for moderate pressure applications.
This series features innovative and unique shut-off capability and
allows full control of the process from complete shut-off to extra
ne regulation.
A choice of three precision stem tapers enables metering at ow
capacities as low as CV= 0.001 with up to 11 handle turns.
This valve is the ultimate solution for precision ow control.
