Legasea hold stock and source a wide range of Subsea Valves, including manually and ROV operated.  

Subsea valves are valves that are installed typically on the seabed or submerged below fixed or floating offshore platforms. They are used to control the flow of fluids, such as oil, gas, and water. Subsea valves can be operated manually or remotely, using a ROV (remotely operated vehicle).

Manually operated subsea valves are typically used in shallow waters where access is relatively easy. They are operated by divers or technicians who use tooling to turn the valve stem. Remotely operated subsea valves are used in deeper waters or in areas that are difficult to access. They are operated by a ROV operator who uses a control panel to move the valve stem.

Subsea valves are an essential part of the offshore oil and gas industry. They help to ensure the safe and efficient operation of offshore facilities.
