The Nu-Torque MSM Series actuators have been designed to meet the requirements of Mil-Spec DOD-V-24657 (SH) and the marine environment. Cast silicon bronze housings, bronze, steel and stainless steel gears, shaft and hardware resist the marine corrosion, and are also the ideal choice for applications requiring low magnetic signature. Motors used are built to MIL-M-17059 or MIL-M-17060 to provide extended life under the worst of shipboard conditions. The gearing is totally enclosed and permanently lubricated.

The MSM Series actuators are compact and durable, reducing the stress on smaller valves where Navy High Shock and Vibration qualifications are required.

Individual compartments for each of the vital sections of the actuator reduce the possibility of damage to the entire actuator due to exposure of one compartment. Limit switch adjustment is accessed by removal of an outer cover, the limit switches remain protected from the environment by an inner barrier. Similarly, the electrical terminations are accessed by removal of an outer cover, integral controls remain protected behind an inner barrier.

MSM series actuators can be supplied for multi-turn and linear applications.
