  • Accurate Operation using continuous sensing technology via solid state hall effect sensors, providing accuracy of 0.3 millimeters. Continuous sensing technology eliminates false alarms by detecting the exact status of the valve.
  • Self Calibration by setting the open and closed position of the valve. Using this feature, a valve position can be calibrated by one person in three minutes, either at the valve (using magnetic key) or remotely via industrial network (without the need to open the switch enclosure).
  • Lower Maintenance Costs by applying factory or user defined device settings to monitor valve cycle count and end point tolerance limits, preventing false alarms and unnecessary diaphragm replacement.
