Safety Warning

Full Product Description

The Paker VSO®- EP Miniature Electronic Pressure Control Unit converts a variable electrical control signal into a variable pneumatic output. Used to control critical pressure, the VSO®-EP replaces manual regulators, needle valves, flow controllers, and vent orifices; providing integral closed loop proportional control. This product uses Parker Hannifin’s patented VSO® proportional valve and offers significant improvements over dual valve controllers. VSO®- EP is used for carrier gas flow control, microfluidic flow control, and for aspirate/dispense applications.
