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.

    *) 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.
