The SD-2002-03 Actuator is built for applications requiring higher rotation range and stronger output, making it ideal for advanced damper and rotary valve control.

With its linear-to-rotary linkage system, it converts actuator stroke into precise angular movement up to 360°, offering greater flexibility in operation. The actuator features a self-locking drive mechanism for stable positioning and a disc spring coupling system to ensure consistent closing force and reliable shut-off.

Driven by a synchronous stall motor, it delivers smooth, accurate, and jerk-free performance, even in continuous modulation applications. Its robust internal construction supports demanding industrial usage.

Encased in a weatherproof aluminium housing (IP65–IP67), it ensures long-term durability in harsh environments.
