Electric Actuators

We offer high-quality electric actuators from renowned manufacturers,
which can be used for a wide range of applications.
From compact solutions to high-performance systems, they enable
seamless control of valves across a wide variety of industries and applications.

Our electric actuators set the standard in precision, reliability, safety and ease of maintenance.
They are characterised by a well-thought-out design, robust construction and durable materials.

We stock a wide range of different models – from compact rotary actuators to high-performance quarter-turn actuators,
each with clearly definable angles of rotation and torques.
Integrated sensors, temperature-resistant materials and water-resistant housings are standard features.
Energy efficiency, smooth start/stop behaviour, precise positioning speed and robust sealing solutions enhance operational reliability and service life.

Furthermore, thanks to their modular design and extensive range of retrofittable accessories, our electric actuators can be individually configured,
enabling tailor-made integration even into complex systems.
Optional parameters include, for example, designs and materials, actuator configurations, operating modes, rotation angle ranges, end-position settings and sensors.
Advanced options include high-precision initiators, redundant power supply and certified protection classes for demanding applications.

Our electric actuators are compatible with the industrial valves we supply.
This ensures seamless integration and consistent operating characteristics from a single source
– from the actuator and valve right through to complete testing and commissioning support.

Applications include, for example, industry, water and wastewater technology, as well as heating and air conditioning systems.
The actuators are particularly well suited to precise positioning and control tasks, reliable remote or local control,
as well as applications with high demands on service life, ease of maintenance and operational reliability.
You can rely on our solutions when it comes to safe, efficient and durable valve control.
