Electropneumatic positioner for pneumatic control-valves
Type 8630 Top Control Continuous works as an electropneumatic positioner for pneumatically actuated control-valves with piston actuators, such as type: 2702, 2712, 2730, 2731, and 2731K, as well as ball- and butterfly-valves with pneumatic rotary actuators. The Burkert Fluid Control Systems product, coupled with a Type-2712 pneumatically operated globe-valve, provides a complete, intelligent p...
Type 8630 Top Control Continuous works as an electropneumatic positioner for pneumatically actuated control-valves with piston actuators, such as type: 2702, 2712, 2730, 2731, and 2731K, as well as ball- and butterfly-valves with pneumatic rotary actuators.
The Burkert Fluid Control Systems product, coupled with a Type-2712 pneumatically operated globe-valve, provides a complete, intelligent process-control/proportional-valve system. Type-8630’s digitally fired positioning-unit has on/off and continuous functionality, and features: a directly connected PID-controlled feedback loop that is integral with the actuator; and a PID Process Tune function, allowing PID-values to be automatically set. Flow accuracy is better than 1%.
Type 8630 can retransmit the process valve status via a 4-20 mA output signal and is available with Profibus DP and DeviceNet interfaces, or without the PID circuit. Type-2712 globe valves come in sizes from 3/8- through 4-in.
