NL Part-turn actuator
The NL series is a favourably priced solution for applications in process plant engineering. The wide range of torques from 1 Nm through to 120 Nm ensures the NL series of actuators is a reliable solution for a multitude of applications.
The design of the housing made of die-cast aluminium and zinc in combination with permanently lubricated gearing with sintered-bronze bearing bushes ensures their suitability for use in a harsh operating environment.
Use of an (optional) electronic position controller ESR-NL can make it easier to integrate the rotary and part-turn actuator into the controls of complex systems.
