What are ball valves used for?

Almost all industrial applications need to be leak-proof. This is particularly important for those that require a tight shut-off mechanism. Examples of such are pure liquid or gas applications, including the gas industry, chemical storage and applications using aggressive fluids. Slurries are not suitable for these valves.

Ball valve parts

Body
This is the frame of the valve that keeps all the parts intact. The part is connected to the piping in the piping system. The main body may have one, two or three parts. We will discuss this difference in a later section.

Stem
The stem is the shaft that connects the inner ball to the handle or actuator. This part transmits the movement of the actual quarter turn force from the actuator to the inner ball part.

Packing
Packing prevents the valve from leaking into the external environment.

Bonnet
The bonnet is the housing that covers the packing and stem. This provides three levels of leakage protection.

Ball
The ball is a hollow ball placed in the middle of the valve. When turned, it will allow the medium to pass or not pass through the valve.
Seat
As the name implies, this section houses the ball mechanism within the valve. The seat provides secondary protection against leakage when the valve is closed.

Actuator
The actuator is located on the outside of the valve body and opens or closes the valve from the outside. It can be opened manually or automatically.

How do ball valves work?

Valves can be bi-directional or more, depending on the number of ports. Bi-directional valves can be bi-directional. That is, there are two seats, one for upward flow and the other for downward flow. There are also ball valves that allow flow in more than one direction. Cost effectiveness is the goal of these valves.

These valves have to be turned a quarter turn to open and allow parts to pass through. Sealing the pipe with this type of valve is to turn another quarter turn, depending on the design of the closure. You can also see more details on how ball valves work in our blog.

Why Choose Ball Valves?

Lowering
This means that higher and more powerful pumps are not required to move fluids and gases. It also means that there is little variation in pressure from high to low, ensuring smooth operation of the pipework components.
No stems
The valve does not include a stem section that pops up or down in response to movement. As a result, no gas or liquid flows out of the pipeline when the valve is closed or opened.
Cost effective
This valve does not cost much, but can be used for a long time. Thanks to the variety of designs, there are even more options.
Versatile
The valve supports high pressures and temperatures. It can withstand temperatures of up to 700 bar and 200°C.
Easy to operate
The valve closes or opens with just 90° of rotation.
Easy to repair
Due to their simple design, especially the top inlet, they are easier to fix and assemble than other valve types. Check out all the top Chinese ball valve manufacturers in this article based on the above factors and choose the right one for your application.
