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.

    Leakage rate:

    Tight sealing

    Characteristics:

    Indicative shaped EQM, best suited for modulating control.

    Material:

    Springs: Stainless steel

    Surface treatment:

    Electrophoretic painting.

    Marking:

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

    Connection:

    DN 15-50: Male threads according to ISO 228. (Separate connections with ANSI flanges and UNC threads.)
    DN 65-125: Flanges according to ASME/ANSI B16.42 Class 150.

    Actuators:

    DN 15-50: TA-Slider 500
    DN 65: TA-Slider 750*
    DN 80 LF/NF: TA-Slider 750*
    DN 80 HF: TA-Slider 1250*
    DN 100 LF: TA-Slider 750*
    DN 100 NF/HF: TA-Slider 1250*
    DN 125: TA-Slider 1250*

    *) 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.
