Stainless Steel Actuators for Industrial Applications

The actuators are constructed from marine-grade Stainless Steel 316 (SST 316) or Titanium, both of which offer exceptional corrosion resistance in subsea and offshore saltwater environments. The material choice depends on the application's depth requirements, weight constraints, and budget considerations.

Both linear and rotary actuator configurations are available. Linear models deliver axial forces ranging from 1,000 N up to 77,500 N, while the rotary actuator provides up to 27 Nm of continuous torque at 0.1-degree resolution. All models use brushless motors and are designed for subsea and industrial automation applications.

Depending on the model, position feedback is provided either via an external rotary resolver mounted on the motor shaft or an integrated absolute 30-bit encoder mounted on the output shaft. The absolute encoder retains position information between power cycles, eliminating the need for re-homing after power loss — critical for deep-sea and unmanned deployments.

The self-compensated linear and rotary actuator models support RS422 (RS485 full-duplex on 4 wires) or RS232 serial communication at 19200 baud. High-force linear models use an external resolver feedback interface. Configurable parameters including baud rate, limit switches, and broadcast frequency are stored in internal EEPROM for flexible integration.

Actuators support multiple power supply configurations: 24 VDC for self-compensated and lower-force linear models, 48 VDC and 230 VDC for the Trunion 1000N series, and 230 VDC for the 60,000 N force linear actuator. The appropriate voltage depends on the required axial force output and system power architecture.

These actuators are engineered for demanding applications including subsea valve actuation, ROV systems, offshore oil and gas infrastructure, marine research instrumentation, underwater robotics, pipeline control, and water tank inspection and cleaning automation. Their corrosion-resistant construction and depth ratings make them suitable for both shallow and ultra-deep deployments globally.
