Control head for decentralised automation of ELEMENT

process valves

• Contact-free inductive valve position registration (Teach function)

• Colour illuminated status display

• Integrated pilot air duct in the actuator

• Fieldbus interface AS-Interface, IO-Link or Bürkert system bus (büS)

• With ATEX II cat. 3G/D / IECEx approval

The device Type 8691 control head is designed for decentralised automation of

ELEMENT Type 21xx pneumatic process valves. The valve position is registered via

a contact-free, analogue sensor element which automatically detects and saves

the valve end position using the Teach function during start-up. The integrated pilot

valve controls single or double-acting actuators. An optional communication inter-

face, AS-Interface, IO-Link or büS (based on CANopen) can be selected.

The design of the control head and the actuator permits internal control air routing

without external piping. Besides the electrical position feedback, the device status

is shown directly on the control head itself through coloured powerful LEDs, even

in difficult ambient conditions.

The housing is easy to clean and features proven IP protection and chemically

resistant materials for use in hygienic processing in the food, beverage and phar-

maceutical industries. Focused on plant wash-down applications, the IP protection

of the housing is supported by 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 environ-

ment.
