Ball Valve VS. Gate Valve

Different industrial valves have different functions. Some valves are used to adjust the flow, some are used to flow and cut off, and some are used to change the direction of the fluid.

At present, ball valves and gate valves are the two most widely used valves. In this article, we will introduce to you the differences between working principle and application. Hope to help you better understand and choose the valve.

What is a ball valve?

Ball valve is a kind of quarter-turn valve. There is a sphere inside the valve body. The sphere rotates a quarter turn with the valve stem to open or close the valve. The inside of the sphere is hollow, which allows fluid to transport.


According to the design, the ball valve can be divided into two-way, three-way or four-way ball valve, which is used for circulation, cut-off, changing the flow direction of the medium, confluence and divergence.

Ball valves are generally used in low-pressure industries. If you need to use it in the high-pressure industry, you need to customize the ball valve that can withstand high pressure.

The ball valve can be made of plastic, brass, stainless steel or carbon steel.

Due to the limited size range of the ball valve, it will be suitable for use in small pipelines, such as water treatment industry, power plant, boiler industry, shipbuilding industry and so on.

What is a gate valve?

The gate valve is a linear motion valve. The valve flap moves up or down to open or close the valve. Gate valves can also be divided into knife gate valves according to their design. The gate valve is a two-way valve with no flow direction requirements.

The gate valve can only be fully opened or fully closed, so the gate valve can only be used for flow and cut-off, and cannot adjust the flow. The gate valve is not easy to be blocked, so it is very suitable for cement plants, paper and pulp and so on.


The gate valve can be made of plastic, cast iron, stainless steel or carbon steel.

The gate valve has a very wide range of sizes, so it can be used in any industry, such as food processing plants, wastewater treatment, oil and gas, and automation industries.


Both ball valves and gate valves have their own advantages, so understanding their functions can help you choose a valve. If you need selection guidance, you are welcome to contact us. We are more than happy to help you.
