Technological advantages for subsea applications

Tightness

Our systems are sized for reliable operation underwater and at high ambient pressure.

Modularity

The components can be flexibly integrated into subsea infrastructures.

Certifications

Comply with international standards such as ATEX and IEEE for safety-critical applications.

Subsea – electric actuators 

WITTENSTEIN offers highly integrated mechatronic systems with extremely robust designs and high-precision calibrations specifically for processing and transporting oil and gas below the sea surface. Our valve actuators, which control many different types of valves, are an outstanding example of this. 
The SSEAC® can be used for throttle, gate, and ball valves.
These actuators are optionally designed with redundancy and are used at depths of up to 3000 meters, with a service life of 25 years.
