Burkert Process Valves Automation (Control)

Burkert offers a smart line of positioners and process controllers for the integrated mounting on process valves. The custom made interface solutions are specifically made for hygienic process environments.

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

The compact positioner Type 8692 is optimized 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 single or double-acting actuators is done without internal air consumption. With integrated diagnostic functions operation conditions of the control valve can be monitored. Through status signals, valve diagnostic messages are transmitted according to NAMUR NE107 and recorded as history entries. The housing is easy to clean and features proven IP protection and chemically resistant materials for use in hygienic processing, in food, beverage and pharmaceutical industries. Combined with Bürkert ELEMENT actuators the unique pilot valve system enables a compressed air recycling that avoids actuator chambers contamination from the environment.

  • Compact, robust stainless Steel design
  • Easy start-up by automatic X-Tune function
  • Contact-free position sensor
  • Integrated control air routing with spring chamber aeration
  • PROFIBUS DP-V1 or DeviceNet communication (option)

Type 8693 Digital electropneumatic process controller for the integrated mounting on process control valves

The compact process controller Type 8693 is optimized 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 actual value of the process factor is directly supplied to the device as 4-20 mA, PT100 or a frequency signal. The process controller calculates the setpoint for the subordinated positioner through the variance comparison. Due to the analogue feedback all analogue values on the controlling level can be transferred. With integrated diagnostic functions operation conditions of the control valve can be monitored. Through status signals, valve diagnostic messages are transmitted according to NAMUR NE107 and recorded as history entries. The parameterization of process controller and positioner can be carried out automatically.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 single or double-acting actuators is done without internal air consumption. Communication interfaces such as PROFIBUS DP-V1 or DeviceNet and analogue as well as binary feedback can also be chosen.

  • Compact, robust stainless Steel design
  • Easy start-up by Tune fuction for position and process controller
  • Contact-free position sensor
  • Integrated control air routing with spring chamber aeration
  • PROFIBUS DP-V1 or DeviceNet communication (option)

Type 8694 Digital electropneumatic positioner for the integrated mounting on process control valves

Compact positioner for integrated mounting on pneumatically operated process valves. Remote setpoint adjustment via a 4-20 mA signal or through AS-Interface. A contact-free analog position sensor measures the position of the valve spindle. Simple installation through automatic tune function and setting through DIP-switch: Close tight function, Characteristic curves selection, Reversal of effective direction, Switching manual /automatic operation, Binary input. Additional parametrisation options are possible through DTM devices. A software interface can be used for, amongst others, linearisation of the operation characteristics by using free programmable fixed points. The valve position indication is shown through LED components. As an option an analogue position feedback can be integrated.

  • Compact, robust stainless Steel design
  • Start-up by automatic Tune function
  • Contact-free position sensor
  • Integrated control air routing
  • Fieldbus interface AS-Interface (option)

Type 8696 Digital electropneumatic positioner for the integrated mounting on process control valves

Compact positioner for integrated mounting on pneumatically operated process valves. Remote setpoint adjustment via a 4-20 mA signal. A contact-free continuous sensor measures the position of the valve spindle. Simple installation through automatic tune function and setting through DIP-switch: Close tight function, Characteristic curves selection, Reversal of effective direction, Switching manual /automatic operation, Binary input. A software interface can be used for, amongst others, linearisation of the operation characteristics by using free programmable fixed points. The valve position indication is shown through LED components. As an option an analogue position feedback can be integrated.

  • Compact, robust stainless Steel design
  • Start-up by automatic Tune function
  • Contact-free position sensor
  • Integrated control air routing
  • Analoge Feedback (option)
