SH Series

Power pack up to 130,000Nm – hydraulic drive for valves and swivel applications up to 180°

The hydraulic rotary actuators of the SH series have been developed for applications up to 130.000Nm and guarantee reliable operation under the most adverse conditions due to their robust design.

In addition to the use as 90° valve actuator, also swing angles up to 180° are possible to move doors, gates, flaps, etc. etc., are possible. Due to the modular design, the actuator can be adapted to customer-specific requirements, for example to achieve fail-safe or quick-close functionality.

The additional use of an EHS Power Pack results in a compact, electrically controllable actuator unit.
