New control system & globe valve

Burkert’s new 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 20mA 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. The valve provides 50-to-one rangeability and is available in sizes from 3/8″ through 4in. The valve is available in ANSI flange and OD tube weld.
