Ball valve handle 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.
