Do You Know About the Gate Valve?

A gate valve is the most widespread type of industrial valves for pipelines. It also is very popular in many applications. But how much do you know about the gate valves? As a gate valves supplier, I'd like to share it with you.

What is a Gate Valve?

A gate valve, also known as a sluice valve, is a valve that opens by lifting a gate out of the path of the fluid. Gate valves got their name from the closure element sliding into the flow stream to provide shutoff and, therefore, acting like a gate.  Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. It represents a linear-motion isolation valve and has a function to stop or allow the flow.

 

Gate Valves Applications

Gate valves are used in almost all fluid services such as air, fuel gas, water, steam, lube oil, hydrocarbon, and all most any services.

A gate valve is the most common valve for water supply systems. Gate valves are used to isolate specific areas of the water supply network during maintenance, repair works, new installations, as well as to reroute water flow throughout the pipeline.

In addition, gate valves can also be used in demanding high temperature and high pressure environments such as power plants, mining industries, and offshore applications.

 

Advantages of Gate Valves

Low Fluid Resistance

Gate valves offer a very small fluid resistance. The gate valve’s body is a straight-through shape that does not alter the flow direction. The minimal fluid resistance is due to the straight inner media channel of the body which allows the medium to flow directly.

 

Wide Range of Applications

The gate valve has a wide range of uses and can be used for steam, oil and other media applications. In addition, the gate valve can also be used for media containing granular solids and high viscosity. It can also be used as exhaust valve and low vacuum system valve.

 

Dual Flow Directions

The flow of gate valves is bidirectional. Their media flow is unobstructed for all directions of the valve body and they aren’t subject to the medium’s directional flow. Therefore, the gate valve is suitable for pipelines where the flow direction may change. In addition, they are easier to install than other more complex valve types.

 

Excellent Sealing Performance

Gate valves can provide better sealing performance. The opening and closing mechanism of the gate valve is faster and more convenient than other valves. The excellent sealing performance of the gate valve also makes the sealing surface of the gate valve generally less corroded when it is fully opened.
