FY301: Smart Valve Positioner

The FY301 is a smart 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 FY301 enabled the choice of several types of flow characterizations, an easy interface between the field and the control room, not to mention several interesting features that considerably reduce the installation, operation and maintenance costs.

Description

The FY301 microprocessor based positioner provides fast and accurate positioning of diaphragm or cylinder actuators. The FY301 produces a pressure output as required to position a control valve according to a 4 to 20 mA input signal supplied by a controller. The FY301 is part of SMAR’s complete 301 series of smart devices.
