• Kofloc Constant Flow Valve For Liquid Model 2600-PPS Series

    Constant Flow Valve for Liquid


    This constant flow valve has been developed for use with liquids. It can control the liquid flow rate irrespective of pressure fluctuations on the primary and secondary sides. It can be used for hot water, as well.


    1.Excellent constant flow valve characteristics for liquids
    The valve composed of high-precision parts permits smooth control.

    2.Immune to the effects of pressure fluctuations
    The constant flow rate is maintained irrespective of pressure fluctuations on the primary and secondary (outlet) sides.

    3.Control is possible from a very small flow rate in the 10 ml/min range.

    4.An air-bleeding structure has been adopted for both upper and lower diaphragm chambers.
    Air bleeding during initial flow rate setting permits high-accuracy control.
