What Is The Opening And Closing Time for Globe Valve
The opening and closing time of a globe valve is the amount of time it takes for the valve disc to move from fully closed to fully open, or from fully open back to fully closed. Because a globe valve uses a linear rising stem and a multi-turn handwheel or actuator, its operating time is usually ...Read more -
Mud Box for Ship Building And Repair
If you’ve ever worked around ships—whether in building, refit, or daily operations—you already know one thing for sure: seawater is never clean. It carries sand, mud, shells, seaweed, paint flakes, rust, and all kinds of surprises you don’t want inside pumps or machinery. That’s exactly why the ...Read more -
What Are The Types of Marine Gate Valves?
Ships rely on many kinds of valves, but gate valves remain one of the most widely used types across marine pipelines. They handle isolation, shut-off, and emergency control in systems that carry seawater, fuel, oil, bilge water, ballast water, and even steam. Because conditions at sea are harsh, ...Read more -
How Ball Valves Are Adapted for Marine Applications
Ball valves are widely used in marine systems because of their simple structure, tight sealing, and quick operation. In ships, they are often found in bilge systems, ballast systems, and fuel transfer lines, where reliable shutoff is crucial. To adapt to harsh marine conditions, marine ball valv...Read more -
How To Improve The Sealing Performance of Marine Storm Valve
A storm valve is vital for preventing seawater backflow during rough weather or high-pressure conditions. Its sealing performance directly affects ship safety. To improve sealing efficiency, start with precision machining. The contact surface between the valve disc and seat must be smooth and pe...Read more -
What Are The Challenges for Gate Valves in Marine Engineering
Gate valves are another common component in marine pipelines, especially when large-diameter flow control is needed. However, they come with challenges that engineers must address. One of the main issues is corrosion and scaling. Constant exposure to seawater and humid environments can cause rus...Read more -

What Are Knife Gate Valves and Why You Need Them in Marine Applications
A knife gate valve uses a sharp-edged metal gate to cut through media and control flow. The “knife” design allows it to pass through viscous liquids, semi-solids, and suspended particles without clogging. When the valve opens, the gate lifts, allowing unrestricted flow. When it closes, the gate c...Read more
