Linear Actuators in Virginia Suppliers and Manufacturers

The product line spans from 1,000 N (220 lbs) in the Trunion entry configuration up to 50,000 N in the 60,000 N Force model. The Trunion series also scales up to 77,500 N, making it suitable for heavy valve actuation, pipeline control, and demanding underwater industrial machinery across a wide range of project requirements.

All actuators are constructed from Stainless Steel 316 (SST 316) or Titanium. Both materials offer superior corrosion resistance in marine and saltwater environments. Titanium is the preferred choice for the most weight-sensitive or highly corrosive deep-sea deployments, while SST 316 provides a robust and cost-effective alternative for standard subsea applications.

Control interfaces vary by model. The Self-Compensated actuator features integrated RS422 (RS485 full duplex) or RS232 serial communication at 19,200 baud with an absolute 30-bit encoder for standalone control. The Trunion and 60,000 N Force models use an external rotary resolver on the motor shaft for position feedback, requiring an external driver and control system.

Yes — the Self-Compensated Linear Actuator features a 30-bit absolute multi-turn encoder mounted on the output shaft that retains position information between power cycles. This is critical for subsea robotics and ROV applications where power interruptions may occur and re-homing routines are impractical at depth.

Power supply options depend on the model. The Self-Compensated actuator operates at 24 VDC. The Trunion 1000N supports 24 VDC, 48 VDC, or 230 VDC, while the 60,000 N Force model operates at 230 VDC. This range of options allows integration with both standard ROV power systems and higher-voltage industrial subsea power architectures.

The 60,000 N Force and Trunion models use Seacon underwater connectors, which are industry-standard for reliable subsea electrical connections in demanding environments. The Self-Compensated actuator uses an MCBH8M SubConn 8-pin underwater connector with a 12-inch MCIL8F whip included, ensuring plug-and-play compatibility with common ROV and subsea system interfaces.
