The valve is used in oil and gas, refining, chemical, steel, and industrial-gas markets. The software uses a single simplified screen to configure and operate the valve, directing up to 255 StarPacs on a daisy-chain network using direct Modbus access. The software has expanded help files and enhanced signature analysis that includes system and component diagnostics for valves, pumps, and piping. Diagnostics check actuator-air pressure, actuator leakage, valve-packing friction, pipe fouling, and pump performance. StarTalk XP also features graphical PID (proportional integral derivative) control for proper valve response to process errors, a tuning screen so users can view and configure controller variables, and alarm explanations.
