Marine Gate Valve
Introduction:
A marine gate valve is a type of valve used in marine applications to control the flow of fluid (usually water) through a pipeline. It is designed to provide a tight seal when closed, preventing leaks and controlling the flow of the fluid.
Marine gate valves are typically made of materials that are resistant to corrosion and other environmental factors such as saltwater, which is commonly found in marine environments. They are often constructed from materials such as bronze, brass, or stainless steel.
Feature:
Marine gate valves are specifically designed for marine and offshore applications. Some of the features of these valves are:Corrosion-resistant: Marine gate valves are made of materials that can withstand the harsh marine environment and are resistant to corrosion, erosion, and chemical attacks.
1.Durable: These valves are constructed with high-quality materials that can withstand high pressures, shocks, and vibrations. They are designed to last for a long time, even under extreme conditions.
2.Tight shut-off: Marine gate valves provide a tight shut-off, which ensures that there is no leakage of fluid or gas. This makes them suitable for applications where safety is critical.
3.Easy operation: These valves are easy to operate and require minimal maintenance. They can be manually or remotely operated, depending on the application requirements.
4.Versatile: Marine gate valves can be used for a wide range of applications, including water, oil, and gas pipelines, and in shipbuilding, offshore drilling, and other marine industries.
5.Various sizes: These valves are available in various sizes, from small sizes for low-pressure applications to large sizes for high-pressure applications. This makes them suitable for various marine applications.
Overall, marine gate valves offer a reliable, durable, and safe solution for marine and offshore applications, making them an essential component in any marine system.

Advantages/Disadvantages |
|
Valve Body |
Bronze |
Pressure resistance, wear resistance, and toughness are higher than those of brass. Bronze has a certain delay in the rusting time of the valve. more expensive than brass |
|
Cast Steel |
The price is higher than cast iron and lower than bronze. It has high mechanical strength and toughness. With heat resistance, corrosion resistance, wear resistance and other special properties. |
|
|
Cast Iron |
Anti-corrosion, it’s cheaper than cast steel and bronze. |
|
|
Valve Bonnet |
Bronze |
Seawater corrosion resistance, a little more expensive than cast steel and cast iron |
|
Cast Steel |
The price is higher than cast iron and lower than bronze. Has high mechanical strength and toughness. It has special properties such as heat resistance, corrosion resistance and wear resistance. |
|
|
Cast Iron |
Not resistant to corrosion and cost less than bronze and cast steel |
|
|
Valve Disc |
Bronze |
Bronze has excellent low temperature resistance, the price is a little more expensive than stainless steel, and the seawater resistance of bronze is better than that of stainless steel |
|
Stainless Steel |
Stainless steel has a strong ability to resist tension, wear and corrosion. Stainless steel is much stronger than copper in material. Stainless steel will not produce corrosion, pitting, rust or wear and high temperature resistance. |
|
|
Valve Stem |
Stainless Steel 304 |
Acid and alkali resistance, high temperature resistance, the price is lower than 316 |
|
Stainless Steel 316 |
Corrosion resistance and acid resistance are better than 304, the price is higher than 304 |
|
|
Hand Wheel |
Cast Iron |
Cost less than bronze and cast steel |

Result |
|
Jerry-built, the valve body wall thickness does not follow the standard processing |
Uneven thickness and material, it’s easy to damage the valve body. |
Strictly in accordance with the standard processing |
Customer use rest assured, to meet user needs, the product has long service life. |
|
Flange manufacturing quality is poor, there are cracks, pores, thickness is not enough and other problems |
Lead to poor wear resistance of the valve, the valve is prone to quality problems, short service life. |
Material selection in strict accordance with national standards |
Valve wear resistance, pressure performance is good, not easy to damage |
|
The valve stem hardness is too low, there are cracks, the valve stem is not round, and the valve stem is not bent and straight. |
Stem sealing surface is easy to damage |
Material selection in strict accordance with national standards |
High stem hardness, no crack, good sealing performance, long service life of the valve. |
|
The manufacturer considers the cost and purchases unqualified standard bolts |
Leaving hidden dangers on the valve can easily lead to accidents. |
According to customer requirements, use standard bolts. |
Use it with confidence, reduce safety hazards and reduce the accident rate. |
Features:
The fluid resistance is small, and the sealing surface is less eroded and eroded by the medium.
It is easy to open and close.
The flow direction of the medium is not restricted, the flow is not disturbed, and the pressure is not reduced.
Durable and easy to use.
