1-1. Overviews
The SVX is an intelligent valve positioner that can be connected to a 4-20 mA controller
output signal line. Since all adjustments can be performed electrically, the relationship
between the input signal and the position of the control valve can be set arbitrarily. Split range
and other special settings are also easy to set up.
