What is the difference between a ball valve and a floating ball valve?

20 Feb.,2024

 

When it comes to choosing the right valve for your needs, it's important to understand the differences between a standard ball valve and a floating ball valve. While both types serve the same basic purpose of controlling the flow of liquids or gases, they have some key differences that can impact their performance and suitability for specific applications. Let's break down the distinctions between these two types of valves.

What is a Ball Valve?

A ball valve is a type of quarter-turn valve that uses a hollow, perforated and pivoting ball to control the flow of a fluid. When the handle is turned to open the valve, the ball rotates to allow the fluid to pass through the valve. When the handle is turned to close the valve, the ball rotates to block the flow of the fluid.

What is a Floating Ball Valve?

A floating ball valve is a variation of the standard ball valve design. In a floating ball valve, the ball is not fixed to the stem but instead floats between the seals. This design allows the ball to move slightly within the valve body, ensuring tight sealing even under fluctuating pressures. .

Key Differences Between Ball Valve and Floating Ball Valve.

1. Sealing Mechanism.

- In a standard ball valve, the ball is fixed to the stem and rotates within the valve body to control the flow.

- In a floating ball valve, the ball floats between the seals, allowing for greater flexibility and tight sealing.

2. Pressure Resistance.

- Floating ball valves are typically designed to withstand higher pressure compared to standard ball valves due to their floating ball design.

3. Durability.

- The floating ball design of a floating ball valve can offer improved durability and longevity compared to standard ball valves.

4. Operating Torque.

- Floating ball valves may require higher operating torque compared to standard ball valves due to the floating design of the ball.

5. Applications.

- Standard ball valves are commonly used in applications where tight shut-off is not required.

- Floating ball valves are often preferred in applications that require tight sealing and high pressure resistance.

Which Valve is Right for You?

When choosing between a standard ball valve and a floating ball valve, consider factors such as pressure requirements, sealing needs, and operating torque. If you need a valve that can handle high pressures and provide reliable sealing, a floating ball valve may be the better choice. However, if your application does not require tight shut-off or high pressure resistance, a standard ball valve may suffice.

In conclusion, the key difference between a ball valve and a floating ball valve lies in the sealing mechanism and pressure resistance.
