Burkert 8697 pneumatic valve control unit

Designed as a more compact version of the type 8690, Burkert’s 8697 pneumatic control unit with position feedback and LED status indication is available as a pneumatic unit or feedback for Element valves with 50 mm actuators - as well as a pneumatic control unit for Classic valves with actuator sizes 40, 50 and 63 mm. The head can also be used as a feedback for Classic actuators of all sizes, from 40 to 225 mm.

The type 8697 replaces the type 1062, which previously offered position feedback (but no pilot) for Classic valves.  It also offers original advancements such as an integrated pilot valve with manual actuation and LEDs for indicating device status. Integrating this head offers a simplified way to create a decentralised automation device, improving overall process speed and allowing independence and therefore creativity in process design, leading to optimised systems.

Using the type 8697 as a pneumatic control unit eliminates the need for a control cabinet with hoses leading to the respective valve. This simplifies system design and minimises the control air consumption for drive switching.

Combining the type 8697 with a process valve from the Element series results in an efficient process with an EHEDG-compliant valve system - with high-level IP protection, as well as an integrated control air supply with additional spring chamber ventilation. The 8697 is aimed at the hygienic and water segments, however its dynamic design allows it to be used in the general process industry.
