4-1 : Smart Valve Positioner (SVP)
4-1-1 : Description
The SVP (Smart Valve Positioner) 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.
