1 860 Electropneumatic positioner for pneumatically actuated control valves Type 860 can be combined with... Type 7 Type 70 Types 70/7/7K Type 800 Piston-controlled globe valve Piston-controlled angle seat valve Piston-controlled diaphragm valve In-line flow sensor The Type 860 works as an electropneumatic positioner for pneumatically actuated control valves with piston actuators, e.g. the series 70, 7, 70, 7 and 7K, as well as ball and butterfly valves with pneumatic rotary actuators. Together with the pneumatic actuator, it forms an optical and functional unit. With its numerous software functions, TopControl Continuous Type 860 may also be used as a process controller with PID characteristics. In this case a process control loop is superposed upon the positioner loop in a cascade structure. The process value is led directly to the TopControl as a standard current signal, frequency or PT-00 signal. The control system may be used for a variety of control tasks in fluid technology. Main functional goups: Position sensor for continuous measurement of the current position in the pneumatic actuator, Microprocessor controlled electronics for signal processing, actual/setpoint comparison, control and valve drive, Pneumatic positioning system for single or double acting actuators.

Type 860 is supplied only with a positioning valve as part of a complete control valve. For the selection of a complete control valve, the following data are required: Order no. of the (see Ordering Table for Type 860 without positioning valve) Order no. of the chosen positioning valve Type 7xx (see e. g. Ordering Tables for Types 70, 7, 7K) The remark: TopControl Control Valve System Page 4/6
