ARCAPRO® positioner - Von Rohr ARCA BV

Analog and digital –precision through innovationARCAPRO ®positionerSince 1917 when it released its patented nozzle-flappersystem, ARCA has been at the forefront of the industry forcontrol valves with positioners. Our advances over theyears have helped make modern positioner technologywhat it is today – and our state-of-the-art digital positionerARCAPRO ® is just the latest in a long line of innovations.Thanks to automatic adjustment in line with the controlvalve and user-friendly parameterization (e. g. direction ofaction, split range or stroke limitation), the system is easyto commission and operate. In addition, a range of variablediagnostics parameters allow preventive maintenancemeasures to be specially planned to avoid plant downtime.Modern communication options (e. g. HART, PROFIBUS,or Foundation Fieldbus) enable function and diagnosisparameters to be sent to process control systems forevaluation.1234567Our innovationClassic or intelligent digital positionerstried-and-tested over many yearsModular, retrofittable accessoryand option modulesIntegrated, pipe-free mountingPatented ARCAPLUG feedback leverMinimal air consumptionUniversal communicationAdvanced online diagnosticsHow you benefit■✔Long service life■✔Low lifecycle costs■✔Optimal adaptionto specific applications andcontrol systems■✔Compact design■✔High mechanical resistance■✔No sensitive piping■✔Self-adjusting■✔No hysteresis■✔Minimal wear and tear■✔Low operating costs■✔Easy adjustment in line with existingplant communication systems■✔All diagnostics data can be read on thedevice or in the control room■✔Self-monitoring of the complete valve■✔Precise planning of maintenancemeasureswww.arca-valve.com5
