Designed as a more compact version of the type 8690, Bürkert's latest innovation boasts a larger scope than its predecessors. The new type 8697 is available as a pneumatic unit or feedback for ELEMENT valves with 50mm actuators, as well as a pneumatic control unit for CLASSIC valves with actuator sizes 40/50/63mm. The head can also be used as a feedback for CLASSIC actuators of all sizes, 40-225mm.
The type 8697 replaces the type 1062, which previously offered position feedback (but no pilot) for CLASSIC valves. Beyond a replacement, the type 8697 offers original advancements such as an integrated pilot valve with manual actuation and LEDs for indicating device status. Integrating this head is the simplest way to create a decentralised automation device, improving overall process speed and allowing independence and therefore creativity in process design, leading to perfectly optimised systems.
The type 8697 asserts itself with mechanical self-adjusting valve position switches as 2 and 3 wire inductive or micro switches. LED integration illustrates switch position. Utilising the type 8697 as a pneumatic control unit creates a decentralised device, eliminating 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 which avowals an EHEDG-compliant valve system with high level IP protection and an integrated control air supply with additional spring chamber ventilation. The hygienic and water segments are the focus of the type 8697; however its dynamic design substantiates its use in the general process industry.
