  • Why do we use ball valves?

  • They may be considered general-purpose flow control valves used for high-temperature applications. As the name suggests, ball valves use a ball to control the flow of substances from one opening to the next.

Brass ball valve

  • Introduction product.

The ball valve is the most common gas control system used to regulate and control methane, natural gas, or propane. It enables users to quickly set temperature applications with high precision using only one input device (in this case – hand). The brass body ensures long durability while preventing rusting, even when exposed to harsh conditions like rainstorms!

  • Applications

Consider brass if you need an automatic ball valve to regulate pressure in your system. It has been used for centuries and can ensure smooth operation with low maintenance costs.

The following are fixtures that use a brass ball valve:

The valves come in many different styles. For example, liquid flow control valves are used for controlling fluids like oil or water with precision and accuracy while still allowing them through when necessary to meet demand levels at any time during operation.

  • Ball Valve Overview

    Ball valves are valves used to control the flow of fluids. They feature a round, hollow ball with a hole drilled through it that controls the flow of material. Ball valves are used in many industries and come in two types: two-piece and three-piece designs.

    Two-piece ball valves are often used for on/off applications as they are compact, easy to install, relatively inexpensive, and maintenance-free. The two pieces consist of a body and a closure member. They provide tight shut-off when closed and have good sealing properties even after long periods making them well-suited for controlling water, steam, or oil applications in both industrial and household settings. Their robust design allows them to handle higher pressures than other valve types, such as gate or globe valves. Additionally, they can be automated easily using an actuator allowing remote operation if necessary.

    Type 1: Floating Ball Valves

    Ball valves are an essential component of any plumbing system and come in various types. One type is the floating ball valve, a two-piece fitting used to control the flow of liquids or gases. These valves are commonly used in water systems, petroleum pipelines, and chemical processing plants.

    Floating ball valves feature two main components: the body and the ball. The body is typically brass or stainless steel and contains ports that allow fluid flow. The ball’s spherical shape allows it to rotate freely within its socket as liquid flows through it, controlling the flow rate by adjusting how far open or closed it is. Floating ball valves are easy to install and maintain due to their simple design; however, they require frequent maintenance due to their susceptibility to wear over time from repeated use.

    Type 2: Trunnion Ball Valves

    The ball valve is a popular and versatile component used in many industries to control the flow of liquids. One common type of ball valve is the two-piece trunnion ball valve. Trunnion valves are designed with an extra support feature, a trunnion mounted between the upper and lower sections of the valve body, providing more stability under extreme pressure or temperature fluctuations. With this additional support, trunnion ball valves have become a preferred choice for large-scale pipelines, oil refineries, chemical processing plants, and other demanding industrial applications.

    Trunnion valves are available in both floating and fixed designs. The construction of these valves allows for minimal operating torque even when fully open or closed, which helps reduce wear on internal components over time.

    Design Differences between Ball Valve 2 Piece Types

    The two main ball valve two-piece designs are floating and trunnion mounted. While both have a similar function, they differ in construction and operation. It is important to consider the differences between these two designs’ features.

    Floating ball valves are constructed from two bodies connected by a single stem. They offer a simple design that requires less maintenance than other valves, such as gate or globe valves. The valve allows the ball to move with pressure changes in the pipeline. In contrast, trunnion-mounted ball valves use two springs to control the ball’s movement within its enclosure; this design ensures smoother flow and prevents leakage in environments where the pressure may fluctuate often.

    Installation Considerations

    Several installation considerations need to be made when considering the purchase of ball valve 2-piece types. The first consideration is the type of pipe material used for the installation. Depending on the environment and specific requirements, different materials should be used, such as brass, carbon steel, or stainless steel. Also, various connection types can be utilized, including threaded, socket weld, or butt weld connections.

    The second consideration relates to size selection and pressure ratings. To ensure optimal performance and operation, choosing the right size and pressure rating valve is essential based on application requirements. Doing so will eliminate the extra burden or risk associated with system failure due to a wrong choice in sizing or pressure rating. Lastly, compatibility between pipe fittings should always be considered when installing any valve system and other components like pumps or tanks.


    The conclusion of the article “Ball Valve 2 Piece Types” provides a brief overview of the advantages and disadvantages associated with these two types. The two-piece ball valve offers many benefits, such as cost efficiency, easy installation and maintenance, and robust construction. On the other hand, its design does limit some of its ability to handle pressure spikes and higher temperatures. Additionally, it is more likely to have leakage problems due to its loose fit between components.

    The three-piece ball valve offers more options when it comes to both pressure handling capabilities and temperature resistance. Still, this increased flexibility comes at a much higher price than the two-piece type. Additionally, while they are better sealed than two-piece valves, they can still be prone to leakage if not properly maintained or installed correctly.
