Control Valves
The NXT2 Network Controller uses on-board communication capabilities to link multiple commercial
valves (via off-the-shelf CAT5, or better cables) for a variety of system types. The NXT2 is configured
for use with Fleck® 2750, 2850, 2900s, 3150, 3900, & 2815 Control Valves, and also supports stager
valves using butterfly or notched cams.
Additionally, using a simple programming sequence, any of the following system types may be configured in the field.
SYSTEM 4 TIME CLOCK – Single tank, no meter. Choose one control valve.
SYSTEM 4 METER DELAYED – Single tank with one meter. Delayed regeneration. Choose one
control valve, one electronic meter and one meter cable.
SYSTEM 4 METER IMMEDIATE – Single tank with one meter. Immediate regeneration. Choose
one control valve, one electronic meter and one meter cable.
SYSTEM 5 INTERLOCK – Two, three or four valves with one meter on each valve. Interlock regeneration – when one valve goes into regeneration, the valve will lock out the remaining valves until
valve is finished regenerating. Choose two, three or four valves, an equal number of electronic meters
and meter cables.
SYSTEM 6 SERIES – Two, three or four valves with one remote electronic meter. Series regeneration – when the lead valve goes into regeneration, then the next valve in-line will follow in sequence
based on the amount of valves in system. Choose two, three or four valves, one electronic meter and
one meter cable.
SYSTEM 7 ALTERNATING – Two valves with one remote electronic meter. Alternating regeneration – one valve in stand by, one in service. Choose two valves, one electronic meter and one meter
cable.
SYSTEM 9 ALTERNATING – Two, three or four valves with one meter on each valve. Alternating regeneration – one valve in stand by the remaining in service. Choose two, three or four valves, an
equal number of electronic meters and meter cables.
