Frequently Asked Questions

Globe valves are commonly used for regulating flow, providing precise throttling and shutoff in systems like seawater cooling, fuel lines, ballast control, and steam circuits onboard ships.

They offer excellent control over flow rates and pressure, making them ideal for systems that require fine regulation and tight shutoff in demanding saltwater environments.

Marine globe valves are typically made from corrosion-resistant materials such as bronze, stainless steel, or duplex alloys to withstand saltwater and aggressive media.

Yes, they are suitable for both, provided the materials are compatible with the media. Bronze and stainless steel options are commonly used for these applications.

It depends on the system. Threaded valves are ideal for smaller pipe sizes and quick maintenance, while flanged valves are preferred in high-pressure systems for a secure, leak-free connection.

Globe valves are designed for throttling and flow control, while gate valves are mainly used for isolation with minimal pressure drop when fully open.

They are built for durability but still require routine inspection and maintenance due to exposure to saltwater and high operating conditions, especially in critical systems.

Marine globe valves should comply with standards such as ISO, DIN, JIS, or those from marine classification societies like DNV, Lloyd’s Register, or ABS.

Yes, especially metal-seated globe valves which are suitable for high-temperature systems such as steam lines and engine room piping.

Manual valves are common for straightforward operations, but actuated globe valves are preferred in automated systems where remote control or faster response is needed.

They provide accurate control of flow into and out of ballast tanks, ensuring safe and balanced vessel operation.

Materials like bronze offer some natural resistance to biofouling, but regular cleaning and maintenance are essential to prevent buildup in seawater systems.
