4700 / 4800

Models 4700P/4700E and 4800P/4800E
Corrosion Resistant Positioners
The Models 4700E/4800E (Electric) and 4700P/4800P (Pneumatic) 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 acutators, the cam is mounted directly on the shaft.
