Pressure Range: Vac to 100 psig*
Flow Range: 0 to 280 slpm
Special configurations over 500 slpm available, consult factory
Flow Resolution: 0.7 slpm per step
Position Resolution: 0.001″ per step
Temperature Range: 32 to 184˚F
Driver: Bipolar chopper drive required
Needle: 3.5˚
Supply Voltage to Motor: 5 VDC
Response Time: 0.95 sec. fully-open to fully-closed
Mounting: In-line, manifold or cartridge
Power Consumption:
3.85 watts nominal only during adjustment
0 power consumption to maintain position
