Burkert”s Type 8630 control system is a digitally fired positioning unit that provides on-off and continuous functionality. It features a directly connected PID-controlled feedback loop integral with the actuator. A PID Process Tune function allows PID values to be automatically set. Capable of retransmitting the process valve via a four to 20 mA output signal, the system is available with PROFIBUS DP and DeviceNet interfaces or without the PID circuit. Combined with the Type 2712 globe valve, the control system provides an intelligent process control/proportional valve that exceeds today’s chemical industry requirements. The valve provides 50-to-one rangeability, is available in sizes from 3/8″ through four inches. The valve is available in ANSI flange, OD tube weld.
