Pneumatic control for decentralised automation of ELEMENT process valves
Type 8697 / Article No. 248830
Product description
The pneumatic control unit Type 8697 is designed for decentralised automation of process valves ELEMENT Type 21xx. Mechanical or inductive limit switches register the valve position. The integrated pilot valve controls single-acting actuators. The design of the control unit and the actuator enables 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 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 pneumatic actuating system enables spring chamber aeration that avoids actuator chamber contamination from the environment.
