Type 8695 Control Head for DeCentralized Automation

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

The control head Type 8695 is designed for decentralized automation of ELEMENT Type 21xx process valves with smaller nominal size.

The registration of the valve position is done through a contact-free Analog position sensor, which automatically recognizes and saves the valve end position through the teach function when starting up. The integrated pilot valve controls single or double-acting actuators.

The design of the control unit and the actuator is specially designed for the requirements of a hygienic process environment and enables an internal control air channel without external tubings.

Besides the electrical position feedback signal the status of the device is shown directly on the control head itself through colored LEDs showing a clear visible valve position status.

As an option a fieldbus interface, AS-Interface, can be chosen. 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.
