A 3 piece ball valve has a round ball inside. The ball helps control how liquids or gases move in a pipe. There are three main parts. The body holds everything together. The ball has a hole in the middle. Two end caps seal the valve and connect it to the pipe. This design is special because you can take out parts fast. You do not need to remove the whole valve. TANGGONG VALVE is a top company for ball valves. They make 3-piece ball valves for jobs like tank switching. They also work for sampling systems. These valves help with heating or cooling in factories.

3 Piece Ball Valve Structure

Main Components
You will find that a 3-piece ball valve has three main parts. The body sits in the center and holds the ball. The ball is a round piece with a hole through the middle. This ball turns to control the flow of liquid or gas. Two end caps attach to each side of the body. These end caps connect the valve to the pipeline and seal the system.
If you look at the TANGGONG VALVE ball valve series, you will see this design in action. The body, ball, and end caps work together to give you strong control over your system. The modular structure means you can take the valve apart without removing it from the pipeline. This makes cleaning, repairs, and part replacements much easier.
Tip: You can replace the ball or seals quickly. You do not need to disconnect the whole valve from your pipes.
Here is a simple breakdown of the main parts:
-
Body: Holds the ball and connects everything.
-
Ball: Rotates to open or close the flow.
-
End Caps: Seal the valve and connect to the pipeline.
TANGGONG VALVE uses strong materials like stainless steel and alloy metals. These materials help the 3-piece ball valve resist corrosion and high pressure. You can trust these valves in tough places like oil and gas plants, chemical factories, and water treatment stations.
TANGGONG VALVE also meets high quality standards. You can see some of the certifications in the table below:

How It Works
You control the flow in a 3-piece ball valve by turning the handle. The handle connects to the ball inside the valve. When you turn the handle, the ball rotates. If the hole in the ball lines up with the pipeline, fluid flows through. If you turn the ball 90 degrees, the hole blocks the flow and stops the liquid or gas.
Here is how the 3-piece ball valve works, step by step:
-
The handle sits on top of the valve.
-
You turn the handle to rotate the ball inside.
-
When the ball’s hole matches the pipeline, fluid moves through the valve.
-
When you turn the handle 90 degrees, the ball blocks the flow and shuts off the line.
The 3-piece ball valve stands out because you can take it apart while it stays in the pipeline. You do not have to remove the whole valve for cleaning or repairs. This saves you time and money. You can reach the ball and seals easily. You can also put the valve back together quickly.
You will notice these benefits:
-
Less disturbance to your pipes during service
-
Easy access to the inside parts for cleaning or repair
-
Fast maintenance and rebuilds
-
Good for places where you need to fix valves often
TANGGONG VALVE builds each 3-piece ball valve to last. The valves use leak-proof seals and strong materials. You get reliable shut-off and smooth flow control. These valves work well in many industries, such as oil and gas, food and beverage, and chemical processing. You can count on TANGGONG VALVE for safe and efficient fluid control.

Three-piece ball valves are the most flexible. You can take them apart for cleaning or fixing. You do not need to remove them from the pipeline. One-piece ball valves have a solid body. You cannot fix them if they break. You must get a new valve. Two-piece ball valves let you do some repairs. But you have to take them out of the pipeline first.
Three-piece ball valves are good for hard jobs. They work in high-pressure steam and hot oil pipes. They can handle air, steam, water, gas, and strong chemicals. This makes them great for oil, gas, and chemical plants. Some two-piece valves can also handle high pressure. But you should check the design and materials before using them.
Note: Always look at the pressure and temperature ratings before picking a valve for your system.
Maintenance and Service
Three-piece ball valves make fixing and cleaning easy. You can check, clean, or fix them while they stay in the pipeline. This saves you time and money. One-piece ball valves cannot be fixed. You must replace them if they stop working. Two-piece ball valves need to be taken out for repairs. This takes more time.
Here are the main points for maintenance:
-
Three-piece ball valves let you fix them in place. You do not have to move the pipeline.
-
One-piece ball valves must be replaced if they break.
-
Two-piece ball valves need to be removed for repairs.
TANGGONG VALVE’s ball valves are known for being strong and easy to use. They have tight seals and are made from good materials. The design lets you turn them on or off quickly. You can trust these valves to work safely and smoothly. If you want fast control and easy fixing, three-piece ball valves from TANGGONG VALVE are a smart choice.
