*Specifications are subject to change without prior notice.

FC-3000series is a small flow control unit for liquids consisting of a control valve and a controller.


  • · Stabilization of flow

    FC-3000 can be installed independently on a branch line without affecting or being affected by the operation of the other branches.

  • · Control of concentration

    FC-3000 achieves easy and stable continuous control of thinning process of chemicals by proportional control on the chemical line and water line.


  • · Control Valve (FCV-3000)

    ·High corrosion resistance
    ·Precise control of small flow
    ·Infiltration resistant construction

  • · Controller (FCA-3000)

    ·High speed control
    ·Flexible operation
