260cc Oil Compensators
Maintain positive internal pressure in oil-filled subsea systems with our Delrin-bodied compensators featuring rolling diaphragm design and SST or Inconel springs, maintaining 0.7–1 bar over full volume.
Keep your subsea systems sealed and operational at extreme depths with NV Mechanics Design's pressure control oil compensators. Engineered for demanding underwater environments—from ROV trenchers to subsea drills—our compensators maintain positive internal pressure, prevent seawater ingress, and ensure reliable performance at depths up to 3,000 meters in British Columbia and beyond.

Maintain positive internal pressure in oil-filled subsea systems with our Delrin-bodied compensators featuring rolling diaphragm design and SST or Inconel springs, maintaining 0.7–1 bar over full volume.
Pressure-compensated rotary actuators with all control circuitry housed internally, rated to 3,000m water depth and delivering 19 ft. lbf nominal torque with 0.1-degree precision.
Oil pressure-compensated linear actuators rated to 3,000m delivering 220–330 lbs axial force, with integrated 30-bit absolute encoders and RS422/RS232 communication protocols.
Rotary actuators designed for integration with external oil compensators, providing precise position control at 0.1-degree resolution for demanding subsea ROV and drill applications.
Reliable proximity switches rated to 6,800m depth, manufactured from SST 316, Inconel, and Titanium for critical signal and position detection on ROV trenchers and subsea drills.
Complete range of remotely operated underwater equipment and components, including actuators with integrated drivers and encoders, all pressure-compensated with oil for depths to 3,000m.
Subsea environments demand components that hold up under thousands of meters of hydrostatic pressure. NV Mechanics Design's oil compensators use a precision rolling diaphragm and SST or Inconel springs to sustain 0.7–1 bar of positive internal pressure, effectively blocking seawater intrusion into oil-filled housings. Built from Delrin for corrosion resistance in saltwater conditions common along the Pacific coastline, they include visual oil-level inspection slots and optional analog or limit-switch sensors to alert operators before oil levels become critical—keeping your ROV systems running deeper and longer.

Their mission is clear: every system ships at the highest quality possible, fits the customer's budget, and is delivered on time to meet expectations.
A subsea oil compensator maintains positive internal pressure inside an oil-filled underwater housing to prevent seawater from entering. It uses a rolling diaphragm and a spring—typically SST or Inconel—to keep internal pressure 0.7 to 1 bar above the surrounding seawater pressure across the full oil volume, protecting sensitive electronics and mechanical components at depth.
