2.1. Type 8697 - Electrical position feedback for CLASSIC valves

The electrical position feedback Type 8697 is optimised for integrated mounting on the CLASSIC 20XX series. Mechanical or induc-

tive limit switches register the position of the valve and give 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 chemically resistant materials for use in hygienic processing, in food, beverage and

pharmaceutical industries.
