Features & Benefits

    Inline design

    Inline flow allows high pressure drops without noise.

    Adjustable flow

    Ensures the design flow.

    Adapters

    For use with most available actuators.

    Technical description

    Application:

    Heating and cooling systems.

    Functions:

    Control EQM
    Pre-setting (max. flow)
    Differential pressure control

    Dimensions:

    DN 15-125

    Pressure class:

    PN 16

    Differential pressure (ΔpV):

    Max. differential pressure:
    1600 kPa = 16 bar (ΔHmax)
    Min. differential pressure:
    Low flow (LF): 24 kPa (ΔHmin)
    Normal flow (NF): 40 kPa (ΔHmin)
    High flow (HF): 80 kPa (ΔHmin)
    (Valid for max. position, fully open. Other positions will require lower differential pressure, check with the software HySelect.)

    Flow range:

    The flow (qmax) can be set within the range:

    DN 15/20 (LF): 120-800 l/h

    Valve plug: Stainless steel
    Valve seat: Stainless steel
    Seat seal: EPDM
    Spindle: Stainless steel
    Δp insert: Stainless steel (plastic components for DN 15-50)
    Δp seat: Ryton plastic
    Springs: Stainless steel

    Surface treatment:

    Electrophoretic painting.

    Marking:

    IMI TA, DN, PN, Kvs, material and flow direction arrow.

    Connection:

    DN 15-50: External threads according to ISO 228.
    DN 65-125: Flanges according to EN-1092-2, type 21. Face to face length according to EN 558 series 1.

    Actuators:

    DN 15-50: TA-Slider 500
    DN 65: TA-Slider 750*
    DN 80 LF/NF: TA-Slider 750*
    DN 80 HF: TA-Slider 1600*
    DN 100 LF: TA-Slider 750*
    DN 100 NF/HF: TA-Slider 1600*
    DN 125: TA-Slider 1600*

    *) Adapter 52 757-907 needed.

    For more details on actuators, see separate technical leaflets.

    KTM 512 can be equipped with adapters for the most common actuators - see "Adapters for actuators".
    The max. lift of the actuator must be checked. In the case of a shorter lift the maximum achieved flow will be decreased. Consult your local sales office for details.
