What Is A Subsea Valve?

Subsea valves need to provide long term reliability in challenging conditions. Valves are designed specifically to be operated and maintained at great depths and to withstand the effects of increased external pressures. Special consideration is necessary for corrosion issues associated with saltwater environments.

Valves for these applications are subjected to stringent type and production testing ensuring the highest possible levels of reliability and performance.

Some of our European partners have dedicated subsea divisions and specialised facilities enabling subsea simulated Hyperbaric testing. Specialised actuators and manual operators are also necessary for subsea operation, ROV interfaces can also be provided to suit the customers’ requirements.
