A marine storm valve is a specialised check valve designed for installation in a ship’s sewage or drainage systems. Its primary function is to prevent seawater from backflowing into the vessel, especially in heavy seas or when the ship is heeled. By serving as a barrier against flooding and contamination through overboard discharge pipes, marine storm valves play a crucial role in maritime safety.

Purpose of a Marine Storm Valve

• Prevents seawater ingress through overboard discharge openings.
• Facilitates the one-way flow of wastewater, bilge, or greywater out of the ship.
• Vital for sewage, greywater, and drainage systems located below the waterline.
