Marine Valves

Marine valves are critical components on ships that control the flow of liquids, gases, and slurries through various piping systems.

They are essential for safe operation of the vessel, including systems such as ballast, bilge, fuel oil, cargo, cooling water, fire-fighting, and domestic fresh water.

Marine valves must withstand harsh marine conditions: high pressure, corrosion (seawater), vibration, temperature variations, and long-term reliability with minimal maintenance.

Common types used on ships include gate, globe, butterfly, ball, check, diaphragm, and control valves — each selected according to function, pressure class, and fluid type.

Proper selection, installation, and regular maintenance of marine valves are vital for ship safety, environmental protection, and compliance with international regulations (SOLAS, MARPOL, Class rules).
