Pneumatic control unit for decentralised automation of

process valves ELEMENT

• Compact design

• Integrated pilot valve with manual override

• Integrated control air routing in the actuator

• Visual position indicator

• With ATEX II cat. 3G/D and cat. 2G/D approval

The pneumatic control unit Type 8690 is designed for decentralised automation of

ELEMENT Type 21xx pneumatic process valves. Mechanical or inductive limit

switches register the valve position. The integrated pilot valve controls single or

double-acting actuators. The design of the control unit and the actuator enables an

internal control air routing without external tubings. Besides the electrical position

feedback, the status of the device is shown directly on the pneumatic control

unit itself. 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. Focused on wash down applications, the IP protection

of the housing is supported by a positive pressure inside the control head.

Combined with Bürkert ELEMENT actuators, the pneumatic actuating system

enables spring chamber aeration that avoids actuator chamber contamination from

the environment.
