Underwater Stainless Steel Actuators in Georgia: A Comprehensive Guide

The actuators are constructed from Stainless Steel 316 (SST 316) or Titanium, both of which provide exceptional corrosion resistance in saltwater and marine environments. SST 316 is ideal for most subsea applications, while Titanium offers an even lighter and more corrosion-resistant option for extreme or long-duration deployments.

Both 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. Communication parameters and limit switch settings are stored in internal EEPROM and can be configured using the provided Windows software utility.

The self-compensated actuators feature a 30-bit absolute multi-turn encoder mounted directly on the output shaft. Unlike incremental encoders, absolute encoders retain position information across power cycles — eliminating the need for homing routines after power loss, which is critical for ROVs and subsea systems where re-initialization is impractical or impossible.

Force output varies by model. The Trunion 1000N delivers axial forces ranging from 1,000 N (220 lbs) up to 77,500 N (7,000 lbs), offering scalable force for diverse applications. The Linear Actuator 60,000 N Force provides up to 50,000 N at speeds up to 200 mm/sec, while the Self-Compensated Linear Actuator delivers up to 1,500 N (330 lbs).

Connector type depends on the model. The Trunion 1000N and 60,000 N Force actuators use Seacon underwater connectors, known for their reliability in deep-sea environments. The self-compensated linear and rotary actuators use MCBH8M SubConn 8-pin underwater connectors, with a 12-inch MCIL8F whip cable included on the linear self-compensated model.

These actuators serve a broad range of subsea industries including offshore oil and gas (valve and pipeline actuation), marine research and oceanography, underwater robotics and ROV systems, water tank cleaning and inspection automation, and subsea infrastructure operations. Their pressure-compensated design and corrosion-resistant construction make them suitable for both commercial and scientific deep-sea applications.
