Actuators AVDU

0%

    Presentation

    AVDU actuators are intended for position control of rotary mixing and ball valves. They have an adjustable auxiliary switch for activating the circulation pump in any actuator position.

    • Switchover between heating and cooling.
    • Switchover between heating and domestic hot water heating.
    • Switchover between various heat sources.
    • Various other central heating devices.

    Features

    • Fits rotary mixing valves or ball valves complying with ISO 5211.
    • The actuators feature four different installation positions on the valve.
    • Resistant to mixing valve blockages.
    • The installation and removal can be mostly completed without any tools.
    • Operation indication with LED lights.
    • An easy replacement of the power cord if damaged.
    • A permanent clutch features a switchover between the automatic and manual operation modes. During a switchover, the actuator is switched off electrically.
    • Option of adjusting the turning direction and operation functions, without interference with the actuator interior.

    Featured functions

    Universal 2- or 3-point operation

    The universal actuator version provides a 2- or 3-point operation. Based on the electrical connection the actuator provides a 2- or 3-point control.

    Clutch for manual operation

    Manual mode clutch of the AVD actuator can be activated by pressing the key. An activated clutch is indicated with a dimmed direction indication LED.

    Quick installation

    Innovative accessories and the installation system provide a quick installation and removal of the AVD actuator to/from the ball valve, mostly without any tools.

    Plug-in connector

    The AVD actuator with an integrated outlet in the housing for connector connection of the power cord. That provides a simple cable replacement in case of damage.

    AUX switch

    The AVD actuator features an extra switch for switching on loads up to 5 A, 230 V~. In order to configure an auxiliary switch, simply remove the manual turning button. The activation/deactivation point can be configured in any actuator position.
