Seawater Discharge Valves: Valves used in marine engineering and shipbuilding require high corrosion resistance and impact resistance. These valves must also meet remote control and intelligent management requirements to adapt to the harsh marine environment. For example, the F500 series seawater discharge valve is used in offshore oil platforms to ensure stable cooling system operation.

Marine Valves: Marine valves must have excellent sealing and corrosion resistance to perform reliably in complex oceanic environments. API 6A check valves and marine ball valves are commonly used in ship seawater cooling systems, fuel supply systems, and ballast water systems.

Seawater Desalination Valves: In seawater desalination processes, valves control the flow of seawater into desalination equipment. These valves are made of corrosion-resistant materials and sealing technologies to extend the lifespan of the equipment. F300 series seawater desalination valves are popular in desalination plants.
