Stainless Steel Actuator Solutions in Connecticut

The linear actuators — including the Trunion 1000N and the 60,000 N Force model — are rated to 6,000 meters of water depth. The self-compensated linear and rotary actuators are rated to 3,000 msw (meters of sea water). All units use oil-based pressure compensation to maintain integrity at rated depth.

NV Mechanics Design offers both linear and rotary stainless steel actuators. Linear models provide axial force output ranging from 1,000 N up to 50,000 N for push-pull subsea tasks. The rotary actuator delivers up to 27 Nm of continuous torque at 0.1° positional resolution, ideal for valve and manipulator applications.

The self-compensated linear and rotary actuators use RS422 (RS485 duplex on 4 wires) or RS232 serial communication at 19,200 baud. All logic and driver circuitry is integrated inside the housing, enabling standalone position control. Parameters are stored in internal EEPROM and configurable via a provided Windows software utility.

Yes. The self-compensated actuators feature a 30-bit absolute encoder mounted on the output shaft — comprising a 14-bit single-turn encoder and a 16-bit multi-turn counter. This means position data is retained between power cycles without the need for homing sequences, which is critical for autonomous and remotely operated underwater systems.

These actuators are engineered for offshore oil and gas, marine research and oceanography, deep-sea ROVs, subsea valve and pipeline actuation, underwater robotics, and municipal water tank cleaning systems. Their corrosion-resistant construction and extreme depth ratings make them suitable for any application requiring reliable actuation in submerged environments.

Yes. The linear actuator range scales from 1,000 N up to 77,500 N in axial force output, and both SST 316 and Titanium construction options are available. Custom configurations, including specific connector types, power supply voltages (24 VDC, 48 VDC, or 230 VDC), and stroke lengths, can be discussed directly with NV Mechanics Design's engineering team.
