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.

Hohe Drehmomente
Hydraulische Antriebe ermöglichen die Übertragung hoher Drehmomente bei kompakter Bauweise und eignen sich damit besonders für große und anspruchsvolle Industriearmaturen.
Hohe Leistungsdichte
Die hydraulische Kraftübertragung ermöglicht eine hohe Leistung bei vergleichsweise kompakter Baugröße.
Präzise und zuverlässige Betätigung
Hydraulische Antriebe ermöglichen eine kontrollierte Bewegung der Armatur und können entsprechend der jeweiligen Anwendung ausgelegt werden.
Definierte Sicherheitsstellungen
Einfachwirkende Ausführungen mit Federpaket ermöglichen eine definierte Sicherheitsstellung bei Ausfall der Energieversorgung.
Robuste Konstruktion
Die Antriebe sind für industrielle Anwendungen und anspruchsvolle Betriebsbedingungen ausgelegt.
Flexible Einsatzmöglichkeiten
Unterschiedliche Baugrößen, Konstruktionsprinzipien, Drehmomentbereiche und Steuerungsvarianten ermöglichen eine Anpassung an die jeweilige Anwendung.
Hydraulisch oder elektro-hydraulisch?
Hydraulische Antriebe
... eignen sich insbesondere dann, wenn eine zentrale Hydraulikversorgung vorhanden ist oder sehr hohe Drehmomente und Stellkräfte benötigt werden.
Elektro-hydraulische Antriebe
... bieten sich an, wenn keine zentrale Hydraulikversorgung vorhanden ist. Durch die Kombination von Elektromotor, Hydraulikeinheit und Steuerung kann eine kompakte und eigenständige Antriebslösung realisiert werden.
Welche Variante geeignet ist, hängt unter anderem von Armatur, Drehmoment, Stellzeit, Schalthäufigkeit, Energieversorgung und Sicherheitsanforderungen ab.
Auswahl des passenden Antriebs
Bei der Auswahl eines hydraulischen oder elektro-hydraulischen Antriebes sind insbesondere folgende Kriterien zu berücksichtigen:
- Armaturentyp
- Nennweite und Nenndruck
- erforderliches Drehmoment
- Losbrech-, Lauf- und Enddrehmoment
- Sicherheitszuschlag
- Schwenkwinkel
- gewünschte Stellzeit
- Schalthäufigkeit
- einfach- oder doppeltwirkende Ausführung
- gewünschte Sicherheitsstellung
- vorhandene Hydraulikversorgung
- elektrische Energieversorgung
- Umgebungstemperatur
- Umgebungsbedingungen
- Stellungsrückmeldung
- Steuerungs- und Kommunikationsanforderungen
- ggfs Explosionsschutz
Wichtig:
Die Eignung hängt immer von der konkreten Armatur und den Betriebsbedingungen ab.
Eine technische Auslegung sollte deshalb immer auf Basis der konkreten Anwendung erfolgen.
Beratung und Auslegung
Die optimale Antriebslösung hängt immer vom Zusammenspiel von Armatur, Antrieb und Betriebsbedingungen ab.
Kähler Industrie-Armaturen unterstützt Sie bei der Auswahl und technischen Auslegung des passenden hydraulischen oder elektro-hydraulischen Antriebes.
Dabei berücksichtigen wir Drehmoment, Stellzeit, Sicherheitsfunktion, Energieversorgung, Steuerung und die konkreten Einsatzbedingungen.
