This Bürkert pneumatic control unit (type 8697) is mounted on top of Bürkert type 20xx valves with CLASSIC 40 mm, 50 mm and 63 mm actuators. The air flow is controlled with a 24V DC signal. The control unit replaces a solenoid valve that otherwise would be used. It features PNP inductive proximity switches and is suited for a 24 V DC feedback voltage. The unit has G 1/8 inch female threaded ports to connect the air lines and an M16 x 1.5 cable gland for electrical connection. External tubing is not needed, because the device has internal control air routing. LEDs show the status of the device. The unit is ideal for use in the food, beverage and pharmaceutical industries thanks to the easy to clean housing, IP65/67 protection and chemically resistant materials. This unit is UL certified.
Pros:
- Compact and durable design
- UL certified
- Integrated pilot valve to control the air flow to the actuator
- Optical position indicator with LED
- Easy to clean and high IP65/67 protection make it suitable for food, beverage and pharmaceutics
Series
Burkert type 8697 is a pneumatic position feedback and control unit, designed for decentralized automation of ELEMENT and CLASSIC process valves. It registers the valve position via mechanical or inductive limit switches. External tubing is not needed, because the device has internal control air routing. LEDs show the status of the device along with the electrical position feedback directly on the unit itself. It is suitable for food, beverage and pharmaceutical industries thanks to the easy to clean housing, proven IP protection and chemically resistant materials.
