with no permanent effect on the
performance of the device.
Operating Ambient
Temperature Range
The proportional control valve is
designed to operate in ambient
temperature, cleanroom environ-
ments. Units are specified to oper-
ate at temperatures of 10° to 65°C
(50° to 149°F). For operation above

System Valving Considerations
The NT Proportional Control Valve,
Model 6300 can be installed with
upstream and/or downstream on/off
valves. However, some precautions
should be taken to ensure longevity
and proper operation of the propor-
tional control valve.
The proportional control valve will
close under two conditions:
1. Zero value setpoint
2. Valve Homing signal
