Type 1067 SideControl Positioner, electropneumatic positioner for pneumatic actuators

The SideControl Positioner Type 1067 serves to position pneumatically actuated positioner valves. SideControl finds applications in many areas by attachment to Burkert process valves or to linear and rotary actuators to IEC 534 or VDI/VDE 3845, or coupled to a separate position sensor or pneumatic positioning system. The compact design of the aluminium body and the availability of versions for low air fl ow capacities enable attachment to positioning valves of small nominal diameter and size. The integral PID process controller may be activated to set up decentralized control loops.

Type 8630 TopControl Continuous

The TopControl Continuous Type 8630 works as an electropneumatic positioner for pneumatically actuated control valves with piston actuators, e.g. the series 2702, 2712, 2730, 2731 and 2731K, 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 8630 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-100 signal. The control system may be used for a variety of control tasks in fluid technology.

Type 8635 SideControl Positioner

The SideControl Positioner Type 8635 is an electropneumatic positioner for pneumatically actuated process valves with linear or part-turn actuators. It is available in the versions 8635 PA and 8635 S. Both versions are executed in two-conductor technology. With Type 8635 PA, communication and energy supply are via PROFIBUS PA whereas with Type 8635 S, the input signal serves for setpoint transmission and energy supply of the device simultaneously. Signal processing, control and actuation of the internal positioning systeme are accomplished with microprocessor-controlled electronics. The software function Autotune implemented therein enables automatic adaptation of the positioner to the control valve in use. The positioner is parametrized and operated comfortably via three operating keys and a plain-text display, or with Engineering-Tools via PROFIBUS PA (Type 8635 PA). It is possible to set up a decentralized control system if a process controller with PID characteristics is used (Type 8635 S). As an option, the SideControl Positioner Type 8635 can be supplied with approval for use in the Ex area (Zone 1) to ATEX. Because of its compact and robust design, the housing is suitable for use in chemical and process engineering.

Type 8692 Digital electropneumatic Positioner for the integrated mounting on process control valves

The compact Positioner Type 8692 is optimised for integrated mounting on the pneumatic actuators in the process valve series Type 23XX/2103 and is specially designed for the requirements of a hygienic process environment. The control air channel is integrated in the actuator without external tubings. The easy handling and the selection of additional software functions are done either on a big graphic display with backlight and keypad or over a PC interface. The Positioner registers the valve position without deterioration through a contact-free, analog position sensor. The control of singleor double-acting actuators is done without internal air consumption. Communication interfaces such as Profi bus DPV1 or DeviceNet and analogue as well as binary feedback can also be chosen.
