Type 8697 Pneumatic Control Unit
Brand: Burkert Fluid Control SystemsThe pneumatic control unit Type 8697 is designed for decentralized automation of process valves ELEMENT Type 21xx. Mechanical or inductive limit switches register the position of the valve.
The integrated pilot valve controls single-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 signal the status of the device is shown directly on the control unit itself via LEDs.
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.
