Underwater Pneumatic and Linear Actuators in Massachusetts

Actuators are available in Stainless Steel 316 (SST 316) or Titanium, both selected for their superior corrosion resistance in marine and saltwater environments. These materials ensure long-term durability in offshore, subsea, and oceanographic deployments where exposure to seawater is continuous.

The Self-Compensated Linear and Rotary Actuators support RS422 (RS485 full-duplex on 4 wires) and RS232 serial communication at 19200 baud. Configuration parameters are stored in internal EEPROM, and a Windows software utility (DCBL_ABS_Control) is provided for setup, calibration, and position control.

Yes. The Self-Compensated models feature a 30-bit absolute multi-turn encoder mounted on the output shaft. This encoder retains position data between power cycles, eliminating the need for re-homing routines — a critical advantage for subsea systems where access for recalibration is impractical.

The high-force linear actuators use Seacon underwater connectors, known for their reliability in deep-sea electrical connectivity. The Self-Compensated models use MCBH8M SubConn 8-pin underwater connectors with a 12-inch MCIL8F whip provided, ensuring secure, waterproof electrical interface at rated depths.

These actuators are engineered for ROVs, subsea valve and pipeline actuation, offshore oil and gas equipment, deep-sea robotic systems, marine research instrumentation, water tank cleaning robots, and underwater infrastructure operations. Their sealed, pressure-compensated design makes them suitable for both shallow and ultra-deep deployments.

Yes. The Linear Actuator Trunion series supports scalable axial force from 1,000 N to 77,500 N, and custom configurations can be arranged by contacting the manufacturer directly. PDF drawings and STEP files are available for download to assist with integration planning and mechanical design.
