21JN1S
21JN1S are proportional valves driven by a bipolar stepper
motor. Thanks to this type of technology it is possible to
minimize the effects of hysteresis and to improve the response
time and the repeatability of performance over time. Minimum
operational pressure is not required. This motorized valve can
be associated to a control driver that can be interfaced with
PLC systems, 4-20 mA and 0-10 V. Please see Driver in Chapter
Control & Automation.
