Side Mounted I/P

The Mark 16IQ is a side mounted valve positioner. The primary module of the Mark 16IQ is the electronic board comprised of the microprocessor, along with the indicating and control elements. The unit is designed so that optional modules for alarms and position feedback are easily plugged in or snapped on. The current command is compared to the internal position feedback signal. By comparing the input and feedback signals, an adaptive controller determines the positioning signal, which follows an optimized algorithm. The parameters for this algorithm are determined from valve and actuator characteristics analyzed during initialization and as modified during the real-time performance of the actuator. The MK16IQ will identify and optimize each valve's specific performance characteristics.
