Series API 3200 G Valve Positioners

The API 3200 G controls the position of a valve or linear actuator by comparing a DC input (control signal) to that of a position feedback potentiometer or slidewire. An SPDT relay provides bi-directional (open-close) signals to drive a motor to open or close a valve.When the valve position, as indicated by the feedback potentiometer, becomes equal to the position as represented by the control input, the relay will go to the neutral position and the motor will halt. A top-accessible multi-turn deadband control allows precise positioning of the motor without hunting or oscillation.

The API 3200 G M01 controls the position of a valve or linear actuator by comparing a DC voltage control signal to that of a voltage feedback signal.

The API 3200 G M420 controls the position of a valve or linear actuator by comparing a DC milliamp control signal to that of a current feedback signal. All versions of the API 3200 G have heavy-duty relay contacts allow the modules to directly control high capacity loads without a secondary device.
