The Veeco SMC-II Automated Valve Positioner enables local manual (keypad) or automated (computer) control of the fluxes generated from Veeco Valved Crackers. It provides fully automated positioning of the source’s needle valve, resulting in flux control, as well as remote control of the valve position via the automated valve positioner’s remote interface. The servo motor assembly provides the actual valve positioning (and, hence, flux control) through a lead-screw assembly that connects to the valved crackers’ needle valve stem.
The LCD front panel of the automated valve positioner allows configuration, calibration and direct user-control of servo motor functions. The user can change modes by cycling through the screens, adjusting parameters and performing valve movement and automatic homing functions.
