ROV Actuators

An actuator converts electrical energy into mechanical motion — either linear (push/pull) or rotary (turning). In ROV and subsea applications, actuators control valves, manipulators, thrusters, and tooling systems. Precision actuators with position feedback, like those from NV Mechanics Design, enable accurate, repeatable motion control at extreme depths.

A ROV valve is an underwater valve designed to be actuated remotely by an ROV rather than manually by a diver. These valves are typically operated using linear or rotary actuators mounted on the ROV or subsea structure. They are common in offshore oil and gas pipeline and wellhead control systems.

A ROV system is a complete remotely operated vehicle platform including the vehicle, tether, control console, cameras, sensors, and manipulator tools such as actuators. ROV systems are deployed for underwater inspection, maintenance, valve actuation, and research tasks in environments ranging from shallow water to depths exceeding 6,000 meters.

NV Mechanics Design offers actuators rated to 3,000 msw (meters of sea water) for deep ROV and robotic applications, and up to 6,000 meters for extreme deep-sea deployments. The self-compensated linear and rotary actuators cover the 3,000 msw range, while the Trunion and 60,000 N linear actuators are rated to 6,000 m.

The self-compensated linear and rotary actuators support RS422 (RS485 full duplex on 4 wires) and RS232 serial communication at 19,200 baud. Configurable parameters, virtual limit switches, and status broadcast frequency (default 10 Hz) are stored in internal EEPROM, allowing flexible integration into existing ROV control systems.

Yes. Both the self-compensated linear and rotary actuators feature a 30-bit absolute multi-turn encoder mounted on the output shaft. This encoder retains precise position information between power cycles, eliminating the need for homing routines after power interruptions — a critical advantage in subsea and ROV applications.
