The pneumatic control type 8697 is designed for the decentralized automation of pneumatic process valves ELEMENT type 21xx. Mechanical or inductive limit switches detect the valve position. The integrated pilot valve controls single-acting actuators. The design of the control and actuator allows internal control air routing without external hoses. In addition to the electrical position feedback, the device status is indicated by LEDs on the pneumatic control itself. The housing made of chemically resistant materials is easy to clean and offers practical IP protection for use in hygienic process technology in the food, beverage and pharmaceutical industries. In combination with Bürkert drives from the ELEMENT series, the pneumatic actuator system enables spring chamber ventilation, which prevents contamination of the drive chambers by the environment.
