• Kofloc Constant Flow Valve For Liquids Chemicals 2600T

    All-Teflon Constant Flow Valve for Liquids/Chemicals


    This constant flow valve has been developed for control of water and chemical flows. It maintains liquid flows constant against fluctuations of both primary and secondary pressures.


    1.Outstanding control of liquid flows at a constant rate
    A valve composed of high-precision components ensures smooth control of flows.

    2.Not affected by pressure variations
    Flows are maintained at a constant rate against fluctuations of both primary and secondary pressures.

    3.Non-metal material (PTFE) used for the wetted part
    This resin (PTFE) is perfect for a part apt to be easily damaged by metal ions.

    4.Small flows from 100-500 ml/min controllable
    Minute flows are also controllable optionally.

    5.Model 2600, all-Teflon type, is compatible with practically all chemicals thanks to the use of a Perfluoro O-ring.
    (There are some operating conditions to be met according to the type of chemical. Be sure to contact us for information before placing your purchase order.)

    6.Bubblers (air bubble purge taps) provided in the upper/lower diaphragm chambers
    Air bubble purge at the initial flow setting stage of operation provides the most accurate possible control.


    1.Ultrapure water analyzers
    2.Environmental instrumentation systems; food/chemical industry equipment
    3.Ultrapure water and chemical mixing systems 

    Standard Applications
    Model 2600-T

    Fluid : Liquids (Mainly H2O)

    Flow rating Control accuracy : 100-500 ML/MIN 0.1-1 L/MIN
                                                      Within ±3% of the set value

    Operating differential pressure : 0.1 MPa or more

    Operating pressure : 0.1-0.5 Mpa

    Proof pressure : 0.7Mpa

    Materials of parts exposed to fluids : fluorocarbon resin, Perfluoro

    Max. operating temperature : 15-35

    Connection end : Rc ¼

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