Shanwu Valve Positioner AVP100-H
The Azbil Sanwu Valve Positioner AVP100 is an intelligent valve positioner that can be connected to the 4-20mA output loop of a regulator. All adjustments are completed by an electronic module, and the relationship between the input signal and the control valve opening can be set arbitrarily, allowing for easy configuration of range and other special applications. The AVP100 model uses a two-wire 4-20mA standard signal and can be directly installed in existing control systems.
