Marine Valves
Marine Valve
A marine valve is a device used to control the pressure, flow and direction of fluid in a pipeline to meet the environmental conditions of a ship. A valve is a control device for a fluid pipeline. Its basic function is to connect or cut off the flow of the medium, change the flow direction of the medium, and adjust the pressure and flow of the medium to ensure the normal operation of the pipeline.
According to the pressure of the valve stem, the sealing surface of the valve plate and the sealing surface of the valve seat are tightly fitted together to prevent the flow of the medium.
Marine valves are designed specifically for use in the marine environment, and they offer several advantages over other types of valves. Here are some of the main advantages of marine valves:
Corrosion-resistant: Marine valves are made from high-quality materials that are highly resistant to corrosion from saltwater and other harsh marine environments.
Reliable operation: Marine valves are designed to operate reliably in demanding marine conditions, ensuring that critical systems function properly at all times.
High durability: Marine valves are built to last and withstand the harsh marine environment, which means they have a longer lifespan than other types of valves.
Easy to maintain: Marine valves are designed for easy maintenance, with simple designs and easy-to-access components.
Safety: Marine valves are designed with safety in mind, and many are equipped with features such as emergency shut-off capabilities to prevent accidents.
Wide range of applications: Marine valves can be used in a wide range of applications, including ballast systems, cooling systems, fuel systems, and more.
Depending on the fluid flow, a variety of valves are used in the piping and equipment systems of ships. haiying offers a wide range of valves for all marine applications with a wide range of uses, including ball valves, butterfly valves, gate valves and check valves.
The butterfly valve is a light duty valve for use on ships operating on fuel, water, lubricating oil or cold water. It is a rotary valve used to control and stop the flow in all ship equipment. Some of the advantages of marine butterfly valves include:
Economical design, fewer parts, easy to maintain and easy to repair
Lightweight and cost effective
Fouling removal, only a small amount of fluid at the pipe outlet, simple opening and closing
A ball valve is a globe valve that uses a rotating ball with a hole to regulate the movement of fluid. Ball valves are used as control valves in the marine industry. Some of the benefits of using marine ball valves include
Have a good service life and provide a strong seal even when the valve is not used for long periods of time
Marine 3-way valves require no lubrication, provide a tight seal and low torque
Withstand and regulate high pressures up to 1000 psi, velocities and temperature fluxes up to 300 degrees Fahrenheit, making them ideal for the marine industry
The globe valve is a linear motion valve that controls flow by starting, stopping, or regulating. Its disc can completely exit the flow path, allowing flow to continue, or stop flow altogether. Marine globe valves are well suited for steam, water, gas and oil operation at high pressures.
The marine globe valve's flow contains changes in direction that result in increased resistance to flow
Withstand pressures up to PN 40 and temperatures up to 700°F, which makes them ideal for marine use
They provide good shutoff and have great use in throttling operations
Gate valves are used only to open or close, so they should not be used to control flow pressure as this can cause them to wear out quickly. Marine gate valves offer excellent performance at high temperatures and pressures
The gate valve profile is a straight-through design that does not change the flow direction, allowing the medium to pass with minimal resistance.
Marine solenoid valves do not seal as well as gate valves, but the flow mechanism of gate valves is faster and easier
Check valves are used in marine sectors to avoid backflow. This guarantees that the system functions perfectly and that destruction does not occur. Marine check valve permits fluid to flow freely in 1 direction and immediately closes when the pressure decreases which is good for vessels.
They're suitable for systems that need to avoid backflow while maintaining a constant flow of fluid.
Marine check valves generally have a pressure rating of up to 600 psi and are available in sizes ranging from ¼” to 4”.
