• Kofloc Constant Flow Valve for Liquid MODEL 2600S & PVC Series

    Constant Flow Valve for Liquid


    This is a constant flow valve developed for liquids, and maintains a constant liquid flow irrespective of pressure changes on the primary and secondary sides.


    1.Excellent constant flow valve for liquids
       The valve is made of high-precision parts for smooth control.

    2.Immune to pressure changes
       The valve keeps the flow constant irrespective of changes in the primary- and secondary-side (outlet-side) pressure.

    3.Control of very small flow from 10 ml/min

    4.Upper and lower diaphragm chambers equipped with airbreathers
       Air breathing during initial flow setting permits high accuracy control.


    2.Environmental measuring instruments
    3.Liquid mixing equipment

    Standard Spesifications

                                   0.1-1 L/MIN                                               0.1-1 L/MIN

    3. Control accuracy Note 1
        Model 2600-S : ±3% F.S.
        PVC : ±3% F.S.

    4. Operating differential pressure : 0.1 MPa or more

    5. Operating pressure : 0.1-0.5 Mpa

    6. Proof pressure : 0.7 Mpa

    7. Materials of parts in contact with fluids
         Model 2600-S : SUS 316, Viton, fluorocarbon resin
         PVC : PVC, SUS 316, NBR, Viton

    8. Operating temperature : 15-35

    9. End connection
        Model 2600-S : Rc 1/4
        PVC : Rc 1/8

    Note: The control accuracy is guaranteed only when the fluid temperature is constant,
    because the viscosity varies with temperature.
