Types of Marine Valve

The marine valve produced by our company mainly include the following types:

Marine Butterfly Valve
Marine butterfly valve is a kind of valve widely used in the marine industry, with many excellent performance characteristics. Butterfly valve is simple in structure, flexible in operation, labor-saving and convenient.

Marine Pressure Reduction Valve
Marine air pressure reducing valve is a safety device mainly used in the pneumatic equipment in the Marine system. Due to the operation of various pneumatic equipments are different during the voyage of the ship, the pressure of the gas required by different equipments is also different.

Marine Gate Valve
Marine gate valves are mainly used for cutting off medium in pipelines, usually designed as a straight line and suitable for straight pipelines. There are also Angle or Y-shaped gate valves suitable for curved pipelines.

Marine Storm Valve
Marine gate valves are mainly used for cutting off medium in pipelines, usually designed as a straight line and suitable for straight pipelines. There are also Angle or Y-shaped gate valves suitable for curved pipelines.

Marine Globe Valve
Globe valve is the most common type of marine valve and one of the most basic valves. Its main function is to control the inlet and outlet of the fluid, which can completely cut off the flow of the fluid. Therefore, globe valves are usually used in pipelines that need to be closed frequently, such as water supply and drainage systems, fuel systems, and lubrication systems on ships.

Features of Marine Valve

Marine Butterfly Valve

Marine butterfly valve have many advantages, including:

Compact Design
Butterfly valves are lightweight and compact, which makes them perfect for situations where space is at a premium, such aboard ships.

Quick Action
Butterfly valves are appropriate for applications that call for frequent adjustments because its quarter-turn action enables quick opening and shutting.

Cost-Effectiveness
Butterfly valves are very inexpensive as compared to other valve types, which makes them a desirable choice for shipbuilders and operators.

Low Pressure Drop
When completely opened, butterfly valves have a low pressure drop, ensuring efficient fluid flow with a low energy loss.

Ease Of Installation And Maintenance
Butterfly valves are simple to install and maintain, which minimises downtime and operating expenses.

Marine Globe Valve

Marine globe valve have many advantages, including:

Robust construction
Marine globe valves are made of high-quality materials such as bronze, stainless steel, and cast iron to withstand the harsh marine environment. They are designed to be corrosion-resistant and are able to withstand high pressure and temperature.

Tight shut-off
Globe valves have a disk that moves up and down to regulate the flow of fluid. The disk is pressed against the valve seat, creating a tight seal that prevents leaks.

Easy to maintain
Globe valves are easy to maintain and repair as they have a simple design with few moving parts. They are also readily available in the market, making it easy to replace parts that have worn out.

Versatile
Marine globe valves are available in a wide range of sizes and materials, making them suitable for different applications such as seawater cooling systems, fire-fighting systems, and fuel systems.

Accurate flow control
Globe valves are designed to provide accurate flow control, making them ideal for applications where precise control of fluid flow is necessary.

Compact design
Globe valves have a compact design, making them ideal for use in applications where space is limited.

FAQ

Q: What are the requirements for a butterfly valve?

A: Butterfly valves used in gas systems require a minimum specified leak rate at a specific operating temperature and pressure. Valves used for liquids require a tight seal to prevent liquid leakage. And butterfly valves for slurry media need to have a reliable wear resistance to ensure tight closure.

Q: What is the use of gate valve in marine?

A: This type of valve utilizes a flat or wedge-shaped gate that moves in and out of the flow path and is often used to control the fluid flow in pipelines. Gate valves are often found in ballast, cargo, and fuel transfer systems.

Q: Do globe valves restrict flow?

A: The operation of a globe valve is governed by the motion of the plug in relation to the valve seat. When the valve is fully open, the plug is lifted off the seat, allowing fluid to flow freely. As the plug moves closer to the seat, the opening through which the fluid flows becomes smaller, restricting the flow.

Q: What is the difference between a safety valve and a relief valve marine?

A: A relief valve opens and closes gradually. A safety valve opens rapidly and does not begin closing until pressure reaches a safe level. Whether you're working with safety valves or relief valves, they're going to need testing.
