Fig. 1: Structure 1
Positioner Type 8694 is an electropneumatic position controller for
pneumatically actuated control valves with single-acting actuators.
Together with the pneumatic actuator, the positioner forms a functional
unit.
The control valve systems can be used for a wide range of control
tasks in fluid technology and, depending on the application conditions,
different process valves from the Bürkert range can be combined with
the positioner. Angle seat valves, straight seat valves, diaphragm valves
or ball valves are suitable.
The position of the actuator is regulated according to the position
set-point value. The nominal position value is specified by an external
standard signal.
