General:
The 4600 Series Pneumatic positioner are field proven
positioners utilizing a precision feedback cam to provide
accurate positioning, very fast response, and customized
control characteristics for control valves. These positioners can
be used with either rotary or reciprocating actuators. When
mounted on reciprocating actuators, a simple, rugged
turnbuckle and lever assembly couples stem motion to the cam.
On rotary actuators, the cam is mounted directly on the shaft.
