Stainless Steel Actuator Options in Virginia

The actuators are constructed from Stainless Steel 316 (SST 316) or Titanium, both chosen for their superior corrosion resistance in saltwater and subsea environments. These materials ensure structural integrity and longevity in deep-sea, offshore, and marine research deployments where material degradation is a critical concern.

NV Mechanics Design offers both linear and rotary actuator configurations. Linear actuators are available in multiple force ratings, from 1,000 N up to 50,000 N axial force. The rotary actuator provides 0.1-degree positional precision at the output shaft with up to 27 Nm of continuous torque, suitable for valve control and manipulator arm applications.

The self-compensated linear and rotary actuators support RS422 (RS485 duplex on 4 wires) and RS232 serial communication protocols at 19200 baud, 8, N, 1 configuration. Status messages are broadcast at 10 Hz by default and can be configured via internal EEPROM. A Windows utility application is also provided for setup and control.

Yes. The self-compensated linear and rotary actuators feature a 30-bit absolute multi-turn encoder mounted directly on the output shaft. This encoder retains position data across power cycles without requiring a homing sequence, which is critical for subsea ROV and robotic systems where re-initialization is impractical after disconnection.

These actuators are designed for subsea and underwater applications including remotely operated vehicles (ROVs), offshore oil and gas infrastructure, subsea valve and pipeline control, marine research and oceanographic instrumentation, underwater robotics and manipulators, and water tank cleaning and inspection automated systems.

Power supply compatibility varies by model. The self-compensated linear and rotary actuators operate at 24 VDC. The Trunion 1000N linear actuator supports 24 VDC, 48 VDC, and 230 VDC. The Linear Actuator 60,000 N Force requires 230 VDC. Customers should confirm power supply requirements against their specific platform's available power architecture before ordering.
