Marine Cast Steel Storm Valve
Marine cast steel storm valves are constructed from cast steel. Cast steel is chosen for its strength, durability, and resistance to corrosion in marine environments. Marine cast steel storm valve is a specific type of storm valve designed for maritime applications, particularly in ships and offshore installations.
Overview
Our Marine Cast Steel Storm Valves are engineered for applications demanding maximum structural integrity and corrosion resistance in seawater systems. Constructed from high-quality cast steel, these valves are designed to automatically prevent the backflow of seawater into shipboard piping or to safely manage overboard discharges, thereby protecting critical equipment and ensuring vessel stability
Main Purpose
The storm valve is typically installed on the ship's hull below the waterline. Its purpose is to close automatically when water pressure from waves or splashes reaches a certain level, preventing water from entering the ship through the hull penetrations like sea chests or other openings. This helps maintain the integrity and safety of the vessel, especially during adverse weather conditions.
Design Features
The valve's design often includes a float mechanism or pressure sensor that triggers the closure mechanism when water pressure exceeds a predetermined threshold. This automatic operation ensures that even if the ship encounters rough seas unexpectedly, the storm valve will activate promptly to protect the vessel from taking on water.
Typical Applications
Main seawater cooling system intake/outlet protection.
Ballast water overboard discharge valves on large vessels.
Firefighting seawater system outlets.
Offshore oil & gas platform piping systems.
Coastal power plant seawater intake screening systems.
Why Choose Cast Steel?
High Tensile Strength & Impact Resistance: Withstands high pressure and potential water hammer, suitable for main seawater lines and large diameters.
Excellent Durability in Harsh Environments: Superior to standard cast iron in corrosive splash zones and continuous seawater immersion (when properly coated or made of alloy steel).
Wide Temperature Tolerance: Performs reliably in varying sea temperatures.
Ideal for Large-Bore, High-Pressure Applications: Commonly used in ship seawater cooling systems, ballast water overboard lines, and offshore platform piping.
