Frequently Asked Questions

What is a subsea control system?

A subsea control system is an assembly of actuators, sensors, and communication electronics used to operate and monitor underwater equipment remotely. It typically includes depth-rated actuators for valve and motion control, position feedback devices such as absolute encoders or resolvers, proximity sensors for state detection, and pressure management components like oil compensators — all designed to function reliably at significant water depths.

What depth ratings are available for these subsea products?

What communication protocols do the actuators support?

Do the actuators retain position information after a power cycle?

What materials are used to ensure corrosion resistance in marine environments?

What is an oil compensator and why is it used in subsea systems?

What power supply options are supported by these subsea actuators?
