Underwater Rotary Actuator Manufacturers in Oregon

The self-compensated rotary actuator supports RS422 (RS485 duplex on 4 wires) and RS232 serial communication at 19200 baud, 8, N, 1. Communication parameters, including status message frequency, are configurable and stored in EEPROM for persistent settings across power cycles.

The rotary actuator delivers 0.1-degree resolution at the output shaft. It uses a 30-bit absolute multi-turn encoder — 14-bit single turn (16,383 counts/turn) plus a 16-bit turns counter — providing extremely fine positional accuracy and reliable multi-turn tracking for demanding subsea applications.

Yes. Both the rotary and linear self-compensated actuators feature an absolute encoder whose position data is retained between power cycles. This eliminates the need for homing routines on restart, which is critical for deep-sea ROV and subsea valve actuation systems where re-homing is impractical.

The deep-rated linear actuators (6,000m models) are available in Stainless Steel 316 (SST 316) or Titanium, both of which offer excellent corrosion resistance in marine and offshore environments. The oil compensators are made from Delrin with SST or Inconel springs for added chemical and salt-water resistance.

These actuators are engineered for ROVs, deep-sea robotics and manipulators, subsea valve and pipeline control, offshore oil and gas infrastructure, marine research instrumentation, and water tank inspection and cleaning robots. They are suitable for any underwater application requiring reliable motorized actuation at depth.

Power supply options vary by model. The self-compensated rotary and linear actuators operate on 24 VDC. The Trunion 1000N linear actuator supports 24 VDC, 48 VDC, and 230 VDC. The 60,000 N force linear actuator operates on 230 VDC, allowing compatibility with a broad range of subsea power distribution systems.
