Piece type ball valves are one of the most commonly used valves in industrial settings. They are found in everything from water and gas pipelines to oil and gas wells. There are a variety of valve sizes available, and knowing which one is right for your application is essential for ensuring a successful installation. In this article, we will cover the different sizes of piece type ball valves and their applications.

What are the different sizes of piece type ball valve?

When it comes to valves, there are a few different sizes to choose from. The most common valve size is 1/2 inch, but there are others including 3/8 inch and 1 inch.

The main difference between the two sizes is that their connecting thread sizes are different.

However, the size of the valve isn’t the only factor when choosing one. You also need to decide what type of valve you need. There are ball valves, check valves and butterfly valves. Each has its own specific uses so be sure to choose the right one for your project!

Which size piece type ball valve is best for my application?

Choosing the right size piece type ball valve for your application can be a challenging task. However, with a bit of research, you can select the perfect valve for your needs. Here are some factors to consider when selecting a piece type ball valve:

Flow rate: The flow rate of the valve is important because it will determine how much water is able to flow through it per minute. High flow rates are needed for high-pressure systems, while lower flow rates are needed for low-pressure systems.

Piston size: The piston size of the valve will determine its opening and closing capabilities. Valve stem with smaller pistons can open and close more quickly, while camlocks with larger pistons can open and close more slowly.

Operating pressure: Valve stem that operate at high pressures need smaller pistons, while camlocks that operate at lower pressures need larger pistons.
