Actuators AVDUS
0%
Presentation
AVDUS actuators are intended for position control of rotary mixing and ball valves. The installation and removal can be mostly completed without any tools.
- For controlling mixing valves in heating or cooling systems.
- 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.

Outlined 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.
