LK 950 actuator 230 Volt mixer drive with 3-point SPDT output

The LK 950 actuator is a reliable and versatile solution for the precise control of mixing valves in heating and cooling systems. With its meticulously engineered design and robust technical features, this mixing valve actuator offers maximum precision and ease of use. Its innovative construction and wide range of applications make it the perfect choice for both professional and residential use.

Innovative features for maximum control

The LK 950 actuator's rotational movements are electrically limited to 90°, enabling precise control. Thanks to its integrated 3-point SPDT (Single Pole Double Throw) design, a high degree of compatibility with various systems is ensured. The reversible scale is particularly practical, allowing for a clear and easily understandable position indication.

Another advantage is the two integrated limit switches, which guarantee durability and safety. This feature ensures that the actuator assumes precise positions and excessive movement is avoided, which in turn contributes to the device's longevity.

Easy installation and flexible mounting

The LK 950 actuator is easy and user-friendly to install. It can be attached directly to the mixer with a single screw. The included stud bolt acts as an anti-rotation device, ensuring the unit is securely fixed. This saves installation time and provides a stable, long-lasting connection.

The mounting position is flexible and can be done in almost any position – only mounting with the drive facing downwards should be avoided. Whether for new installations or as a replacement for existing components – the mixer drive fits most standard mixers, making it universally applicable.

Versatile use thanks to manual operation function

A special feature of the LK 950 actuator is the ability to switch to manual operation in the event of a control system malfunction. An easily accessible rotary knob on the housing disengages the gearbox, allowing the mixer to be moved manually to the desired position. This provides a practical solution in emergencies and ensures continuous monitoring, even if the electrical system should fail.

Manual operation is not only functional but also particularly easy to perform. This makes the actuator a reliable companion, even under difficult conditions.
