General:
The 8200 Series Electropneumatic positioner are produced
with Masoneilan Technology.
The positioner is an electropneumatic force-balance device
which provides an accurate means of obtaining at any time a
valve stem position corresponding to a theoretical position
envisaged for a DC input signal. In addition, the positioner
provides a convenient means of split-ranging operation for
several valves (usually two) from a single signal emitted by a
single controller. The positioner may have either direct or
reverse action on either direct or reverse actuators.
