The Nu-Torque MS Explosion-Proof Series actuators have been designed to meet the requirements of the Mil-Spec DOD-V-24657 (SH) and the marine environment. Cast 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.MS Actuator Motors used are built to MIL-M-17059 or MIL-M-17060 to provide extended life under the worst shipboard conditions.

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

The MS Explosion-Proof Series actuator can be supplied for quarter-turn and multi-turn applications.
