FY302: Foundation Fieldbus Valve Positioner

The FY302 is from the first generation of Fieldbus devices. It is a control valve positioner for pneumatic valve in a Fieldbus system. The FY302 produces a pressure output as required to position a control valve according to an input received over the Fieldbus network or internal controller.
The Fieldbus technology used in the FY302 enables, an easy interface between the field and the control room and several interesting features that considerably reduce the installation, operation and maintenance costs.

Description

The FY302 is a Fieldbus valve positioner for Single (spring return) or Double acting Linear motion
type control valves e. g. Globe, Gate, Diaphragm, Pinch or Clamp and Rotary motion type control
valves e. g. Ball, Butterfly or Plug with pneumatic type actuators e. g. Diaphragm, Piston, Vane, or
Bellows. It is based on a field-proven piezo flapper and non-contacting Hall-effect position sensor
that provides reliable operation and high performance. The digital technology used in the FY302
enabled the choice of several types of flow characterizations, an easy interface between the field
and the control room and several interesting features that considerably reduce the installation,
operating and maintenance costs.
