Long Performance Miniature Pressure Controllers Pressure Controllers Designed for industrial and OEM instrument applications, the VSO®-LP Long Performance Pressure Controller delivers integral closed loop proportional control with the highest level of accuracy and stability. With an extra internal exhaust valve, the VSO®-LP provides rapid depressurization and response for precise pressure control. The VSO®-LP offers the flexibility to control pressure or flow, replacing manual regulators, flow controllers, and needle valves. This product uses Parker Hannifin's patented VSO® proportional valve for precise and consistent performance. Features • Integrated exhaust valve provides rapid depressurization and response • Tested for long life to improve system availability Electronic Pressure Control Low power consumption reducing heat generation Customer configurable for pressure control or flow control Offers silent operation to reduce overall system noise Analog control for added design flexibility RoHS compliant RoHS Product Specifications Physical Properties Valve Technology: Thermally compensated proportional valve, solenoid exhaust valve Media: Non-corrosive gases Operating Environment: 32 to 131°F (0 to 55°C) Storage Temperature: -40 to 149°F (-40 to 65°C) Length: 1.49 in (37.8 mm) Width: 1.58 in (40.1 mm) Height: 2.78 in (70.6 mm) Weight: 6.2 oz (183.4 g) Porting: 10-32 female ports Metric adaptor available Electrical Power: 24 VDC + 10% Input Control Signal: 0-5 VDC standard Monitor Output Voltage: 0-5 VDC Current Requirement: <550 mA Electrical Connector: Molex 6 pin miniature connector 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 Performance Characteristics Pressure Ranges: 0-15 psig (0-1.03 bar) 0-100 psig (0-6.89 bar) (Effective control range is 10%-100% of full scale) Pressure Accuracy: + 1.5% Full Scale max Response: <15 ms (Response time to target pressure is output volume dependent) Linearity: < +1.5% Full Scale VSO is a registered trademark of Parker Hannifin Corporation.

Electronic Pressure Control VSO®-LP Long Performance Miniature Pressure Controllers Installation Guide The VSO®-LP is a dynamic pressure controller that uses proportional valve technology to supply an accurate and stable pressure source for a variety of application requirements. It also incorporates a secondary pressure release valve that automatically reduces the pressure rapidly by venting it to atmosphere as required. 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...

With Internal Vent. A vent is required when the application does not consume any gas. For example, pressurizing a piloted regulator.
