Bronze Ball Valves

Bronze Ball Valves are a popular and reliable choice for marine environments due to their excellent resistance to corrosion, especially when exposed to saltwater. Unlike standard brass, bronze offers greater durability and resilience against dezincification, making it a long-lasting option for critical systems on ships, offshore platforms, and coastal installations.

In marine applications, bronze ball valves are commonly used in seawater intake lines, bilge systems, cooling circuits, and ballast water control. Their strength, non-sparking properties, and compatibility with a wide range of fluids—including saltwater, fuels, and oils—make them a versatile and trusted component across commercial and industrial vessels. With options for threaded, flanged, or weld-end connections, bronze valves provide a dependable solution where reliability and corrosion resistance are essential at sea.

Frequently Asked Questions

A marine ball valve is a type of shut-off valve designed for use in marine environments. It controls the flow of fluids such as seawater, fuel, or oil through a rotating ball mechanism.

Marine ball valves are typically made from bronze, aluminium bronze, stainless steel, or duplex/super duplex—all chosen for their corrosion resistance in saltwater environments.

Yes, marine ball valves are designed to withstand the harsh conditions of seawater exposure. Material selection and internal coatings help prevent corrosion and biofouling.

They are commonly used in sea water intake lines, cooling systems, fuel lines, ballast systems, bilge systems, and firefighting systems on ships, yachts, and offshore platforms.

Yes, quality marine ball valves are manufactured to comply with standards such as DNV, ABS, BV, Lloyd’s Register, and IMO regulations, depending on the application and vessel type.

Absolutely. With the appropriate sealing materials (such as Viton or PTFE), marine ball valves are suitable for diesel, hydraulic oil, and lubricants.

Marine ball valves are specifically designed for corrosive and humid environments, offering superior durability and resistance to pitting and salt damage.

Yes, many marine ball valves can be fitted with electric or pneumatic actuators, especially for remote or hard-to-access locations on board.

Some bronze and stainless steel marine valves also carry WRAS approval, making them suitable for potable water systems on ships and marine facilities.

Regular inspection, cleaning, and lubrication of the valve and seals are recommended. In saltwater applications, it’s important to monitor for signs of corrosion or wear.

Marine ball valves typically range from PN16 to PN40, with high-pressure options available for specific engine room or hydraulic systems.

Yes, fire-safe certified ball valves can be used in fuel lines or engine room systems, ensuring continued function and sealing during high-temperature events.
