Stainless Steel Pneumatic Actuators for Industrial Use

The high-force linear actuators are available in Stainless Steel 316 (SST 316) or Titanium construction, offering excellent corrosion resistance in marine and subsea environments. The self-compensated models feature sealed housings designed for long-term underwater deployment in demanding conditions.

The self-compensated linear and rotary actuators support RS422 (RS485 duplex on 4 wires) and RS232 serial communication at 19200 baud. Configuration parameters including virtual limit switches and broadcast frequency are stored in internal EEPROM, allowing flexible integration into ROV and subsea control systems.

Yes. Both the self-compensated linear and rotary actuators feature a 30-bit absolute multi-turn encoder mounted on the output shaft. Position information is retained between power cycles, eliminating the need for re-homing routines — a critical advantage in subsea and ROV applications where power interruptions may occur.

NV Mechanics Design's linear actuators span a wide force range. The self-compensated model delivers 1,000N to 1,500N (220–330 lbs), the Trunion 1000N scales from 1,000N up to 77,500N, and the heavy-duty 60,000N Force model delivers up to 50,000N axial force — catering to light ROV tasks through to heavy subsea industrial machinery.

Yes. All models in the range are well-suited for subsea valve and pipeline control applications. The precise position feedback via absolute encoders and configurable software limit switches allow accurate, repeatable valve positioning. They are commonly deployed in offshore oil and gas infrastructure and underwater pipeline control systems.

Yes. NV Mechanics Design provides detailed documentation including assembly drawings, STEP files, interface and integration guides, and Windows utility software for setup. For custom force, stroke, voltage, or connector configurations, customers are encouraged to contact the manufacturer directly at their British Columbia, Canada headquarters.
