Structure
The control head Type 8691 can control single or double-acting
process valves and has been optimized for the integrated modular fitting
of series 21xx process valves (Element) . Various expansion stages are
possible thanks to the modular design.
For installation on the 20xx series (Classic) there is a special model
which is described in chapter “5.3”.
The valve position is recorded via a contactless, analog sensor element
which automatically detects and saves the valve end positions by means
of the teach function during start-up.
