The Nu-Torque MI Explosion-Proof Series actuators have been designed to meet the requirements of the marine environment. Cast ductile iron or silicon bronze housings, bronze and steel gears, shafts and hardware resist the marine corrosion and are also the ideal choice for applications requiring low magnetic components. MI Actuator Motors used are built to IEEE-45 standards to provide extended life under the worst shipboard conditions.

The MI Explosion-Proof Series actuators are compact and durable, reducing the stress on smaller valves.

The MI Explosion Proof Actuator series can be supplied for quarter-turn and multi-turn applications.


  • Local controls (pushbuttons and lights — local/remote switch)
  • PROFIBUS, ModBus® Serial communication
  • Right angle gearbox for limited overhead locations
