The Parker VSO®- GC Miniature Electronic Pressure Controller converts a variable electrical control signal into a variable pneumatic output. The internal integration of the VSO®- GC has been optimized for low flow applications and applications requiring minimal volume. Used to control critical pressures and flows, the VSO®- GC replaces manual regulators, needle valves, flow controllers, and vent orifices, providing integral closed loop proportional control. Using Parker Hannifin’s patented VSO® proportional valve for precise control, the VSO®- GC is an ideal choice for carrier gas flow control, microfluidic flow

control, and for aspirate/dispense applications.
