Gate valves are the safety devices that are used to completely shut down the flow of the fluid or to completely open the fluid flow to provide the heavy flow of the fluid in the pipeline. There are just two positions of van cổng they are either fully opened or fully closed. They remain closed to shut down the fluid flow and remain open to provide the complete flow of the fluid in the pipeline. They are placed in the pipeline where they remain open or closed for a long time. They require a short time period to switch between these two positions. They are installed in that area where there is no need to change the fluid flow frequently.

The gate valves are used in the plumbing and pipeline appliances. They are made up of iron body stainless steel, and also some are made up of brass. All these are used in plumbing and pipeline applications. They are very useful to change the flow of fluid in pipelines. But they are not used at the places where the flow of the fluid has to be changed instantly.

Uses of gate valve
There are many applications and systems where we have to control the fluid flow due to many reasons. If the fluid flow becomes more than the normal limit, then it may cause many difficulties. There are also many other uses of gate valves. Some of them are the following.

• In Oil extraction
• Gas extraction
• In medical and laboratory use
• In different factories
• Processing plants and water treatment areas
• In food production plants
• In food catering services
• In marines and offshore

Gate valve is very important, and it is used in the above-mentioned areas to control the flow of the fluid in different pipelines. If the flow of the fluid is not controlled, it may exceed the normal limit, and then it causes harm and hazards. To prevent these hazards, gate valves are used. By using gate valves, we can control the flow of the fluid in the pipeline and in the required areas. The van cổng is used in the plumbing and pipeline appliances. They are made up of iron body stainless steel, and also some are made up of brass.

Gate valve works by inserting the gate or the disk in the pipeline to stop the fluid flow in the pipeline. This gate or disc is the physical barrier to stop the flow of the fluid in the pipeline. When you want the flute to flow at full speed, then the gate wall is turned off, and the gate or the disk is removed from the pipeline to continue the fluid flow. In this way, the gate valve is turned on or off to stop or to continue the fluid flow in the pipeline. It is very important in those areas where we want to change the flow of the fluids at different time intervals.

Types of gate valves
There are different types of van cổng that we can use according to our requirements and our needs. Different types are used in different applications and different systems. We cannot use the same type in all the systems. There are the following important types of gate valves.

Wedge gate valves
The wedge gate valve is the most common type of gate valve which can be used in the plumbing and the pipeline system in houses and in different industries. We can use these Gate valves in different areas of our houses and in different industries where we want to change the pressure of the fluid in the pipeline. It is also designed to open or close the pipeline for fluid flow.

Split gate valves
These gate valves are used in corrosive liquids and non-condensing gases. In this Valve, the disk is made up of two pieces that are held side by side by a spring. It helps a lot in achieving a tighter seal very easily.

Parallel gate valves
Parallel gate valves are like wedge gate valves, but the difference is that the two disks are placed at the 90-degree angle in the direction of the fluid flow. It is used in different plumbing systems and pipelines in different industries and in different factories.

Knife gate valves
It is a very important and famous type of gate valve that is made to use for very thick fluids such as slurry liquids or powder carrying liquids. Its discs are like knives that easily cut of the thick fluid while closing. The normal gate valve can be difficult to close when the fluid is very thick. But the knife-like Valve can easily cut off the thick fluid while closing.

Flanged gate valve
It is also the most common and the most important type of Gate valve. In this type, the body of the Valve Is attached to the upper side of the world where the handwheel is connected that gives access to the moving part of the Valve. It is used in different industries and in different plumbing systems.

Conclusion
Gate valves are the devices that are used to completely shut down the flow of the fluid or to completely open the fluid flow to provide the heavy flow of the fluid in the pipeline. They are placed in the pipeline where they remain open or closed for a long time. They require a short time period to switch between these two positions. They are made up of iron body stainless steel, and also some are made up of brass. All these are used in plumbing and pipeline applications.
