The electrical position feedback Type 8697 is optimised for integrated mounting on the CLASSIC 20XX series.
Mechanical or inductive limit switches register the position of the valve und gives an electrical feedback signal to the control system.
Besides the electrical position feedback signal the position of the valve is visually shown via LEDs.
The housing is easy to clean and features proven electrical IP protection and chemicallyresistant materials for use in hygienic processing,
in food, beverage and pharmaceutical industries.
