Miniature Electronic Pressure Controllers Pressure Controllers Typical Applications The 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, vacuum pump control, and for aspirate/dispense applications. Features • Offers silent operation to reduce system noise levels • Ensures high accuracy and unparalleled resolution for improved results • Tested for long life to improve system availability Electronic Pressure Control Carrier Gas Pressure Control Offers internal closed loop control to minimize system development time OEM application-specific configurations available Analog control for added design flexibility RoHS compliant ■sf 1 Rnl4<t Air over Liquid Flow Control Electronic Pressure Regulation Vacuum Generator Control Electrical Main Voltage: 24 VDC + 10% Input Control Signal: 0-5 VDC standard Monitor Output Voltage: 0-5 VDC Maximum Current Requirement: < 400 mA Electrical Connection: RJ-45 Wetted Materials Manifold: AL 6061-T6, FKM, 302 Series SS Valve: FKM, 300 Series SS Brass 36000HT Tubing: Ester Based Polyurethane Sensor: Glass, Silicon, Silicone, Polyphenylene Sulfide Product Specifications Physical Properties Valve Technology: Thermally compensated VSO® proportional valves.

VSO®-EP Miniature Electronic Pressure Controllers Electronic Pressure Control VSO®-EP Flow Capability Sizing Charts How Flow Effects Pressure Control The flow curves illustrate the flow capabilities of the three models of pressure controllers. Pressure control using a constant flow approach requires the system to manage pressure drops across a variable orifice and a fixed orifice (see below).

Electronic Pressure Control VSO®-EP Miniature Electronic Pressure ControllersInstallation Guide The VSO®-EP is a dynamic pressure controller that uses proportional valve technology to supply an accurate and stable pressure source for a variety of application requirements. Installation of this device requires the completion of a few easy steps. They are as follows: • Ensure that the gas is non corrosive, clean and dry. • Connect the gas supply to the Inlet Port on the VSO®-EP. • Connect a line requiring the controlled pressure to the Outlet Port on the VSO®-EP. • Pneumatic ports are 10-32 UNF-2B...
