The D400 series digital positioner is designed to work with both rotary and linear pneumatic valve actuators. A digital positioner provides sophisticated control designed to integrate with HART, FOUNDATION Fieldbus or Prof bus communication. The D400 requires instrument quality compressed air and is extremely air efficient.
Although the D400 digital valve positioner is quite sophisticated, it is simple to mount and calibrate.
