SVP3000 AlphaPlus Smart Valve Positioner
a high performance microprocessor based current-to-pneumatic valve positioner,receives a dc signal from a control device & modulates the supply pressure to a control valve actuator,provides accurate valve position proportional to dc current input signal.

Custom Characterization:Optimize to valves overall flow characteristics
•Custom characterization of SVP output to valve•User definable•Useful for butterfly, Sanders oror ball valves with fixed & poor flowcharacteristics•16 segments set through an SFC•standard SVP function
Custom characterization

Split Range Application -SVP3000 ideal application
•Lowest power requirement in smart positioner market•low impedance like conventional devices.•easily applied for split ranging•non-interactive zero & span adjust•Ideal for gap or gap setting control•example: 2 valves in same loop•reduce installation & setup time•Typical for vinyl or ethelene monomerplants
