Advantages and Disadvantages of Floating Ball Valve

Floating Ball Valve

As you may know, ball valves are commonly used in many industries for controlling flow. The floating ball valve, in particular, is a popular choice that offers several advantages and disadvantages over other ball valve options. If you want to learn more about this type of valve, you’ve come to the right place. In this blog post, we’ll explore the benefits and drawbacks of floating ball valves so you can decide on your specific application.

What is Floating Ball Valve?

A floating ball valve is used to regulate or shut off the flow of liquid or gas. It has two main components – a lined spherical body and an integrated seat that seals the opening. The ball within the valve rises and falls with pressure, ensuring an even seal no matter what conditions it’s subjected to. This makes it ideal for use in high-pressure systems where precision is essential.

Advantages of Floating Ball Valve

Cost-Effective: Floating ball valves are a popular choice for their cost-effectiveness compared to other valves. They are typically less expensive to manufacture and install than trunnion-mounted ball or gate valves.

Easy to Maintain: Another benefit of the floating ball valve is that they are relatively easy to maintain. When maintenance is required, the valve can easily be disassembled and the ball and seals replaced without removing the entire valve from the pipeline.

Great for Low-Pressure Applications: Floating ball valves are also ideal. This is because the ball in a floating ball valve is not fixed to the stem, allowing it to move freely. As a result, the valve requires less force to operate, which is useful for low-pressure systems.

Good Flow Control: This type of valve design offers excellent control over the fluid flow, making it ideal for applications where precise flow control is essential. This is due in part to the design of the ball that provides a large sealing area for the valve seats.

Disadvantages of Floating Ball Valve

Limited Temperature Range: Floating ball valves are not suitable for high-temperature applications. This is because the ball in a floating ball valve is not fixed to the stem, and it can move around at high temperatures, which can cause the valve to fail.

Limited Pressure Range: Similarly, floating ball valves cannot handle high-pressure applications. They are not as strong as other valves and may deform or fail under high-pressure conditions.

Limited Seat Material Options: The seating materials used in floating ball valves are also limited compared to other valve types. This is because the valve design requires the seats to be bonded to the valve body.

Limited Chemical Compatibility: The materials used in the valve’s construction limit the chemical compatibility of the valve. For instance, floating ball valves may not be suitable for use with chemicals that can react with the seat materials.


Floating ball valves offer several advantages over other valve types, such as low cost, ease of maintenance, and excellent flow control. However, they also have several limitations, such as temperature and pressure limitations and limited chemical compatibility. Choosing the appropriate valve for your process largely depends on the application you have in mind. This blog post has given you a better understanding of the pros and cons of floating ball valves and helped you make an informed decision for your application.
