*Specifications are subject to change without prior notice.

FC-100series is a liquid flow control system which consists of "FCV-200 Flow sensor + Control valve" and "FCA-100 Controller". FC-100 series is suitable for water and low viscosity liquids.
And it maintains stable flow even supply and/or load varies.


  • · Cost effective flow control system

  • · Space saving;

    Flow sensor and control valve are integrated. This saves piping space.
    DIN 24 x 48 size Controller saves panel space.

  • · Full open/close type valve is adopted, and can be used as Shut-off valve which has been indispensable.

  • · Drain out of line fluid by air purging possible

  • · Lead-free solder has become reality.

  • · High reliability of electronics

  • · EMC Compatible standard: EN61326-1

Recommended Applications

Continuous and stable feeding of cooling water for;

  • · Semiconductor / FPD plants and machinery
  • · Chiller units for air-conditioning
  • · Others
