Ballast Valve

Ballast valves are a type of nonpowered valve that falls under the supply class of Valves, Nonpowered in the supply group Valves. These valves are specifically designed for use in ballast systems, which are used to control the stability and trim of ships and other marine vessels.

Ballast valves are responsible for regulating the flow of water into and out of the ballast tanks. These tanks are used to adjust the weight distribution of the vessel, allowing it to maintain stability and control its draft. By opening or closing the ballast valves, the amount of water in the tanks can be adjusted, which in turn affects the vessel's buoyancy and trim.

These valves are typically made of durable materials such as stainless steel or bronze to withstand the harsh marine environment. They are designed to be reliable, easy to operate, and resistant to corrosion and fouling.

In summary, ballast valves are nonpowered valves used in ballast systems of marine vessels to control the flow of water into and out of ballast tanks, thereby maintaining stability and trim.
