Which is better trunnion ball valve or floating ball valve?

When it comes to selecting the right type of ball valve for your application, trunnion ball valves and floating ball valves are two popular choices that engineers and procurement specialists often debate. Each design has its benefits and limitations, making it essential to understand their differences and applications to make an informed decision.

Understanding Trunnion Ball Valves

Trunnion ball valves have a fixed shaft or trunnion that supports the ball. This design allows the valve to operate under high pressure and larger sizes without compromising on performance. The trunnion translates any pressure force on the ball, ensuring that it remains stable within the valve body. The lower operating torque required for opening and closing makes it ideal for large-diameter applications.

Advantages of Trunnion Ball Valves

• Ability to handle high pressure and high flow rates.
• Lower operating torque, making them easier to operate.
• Reduced wear and tear, leading to longer service life.

The Role of Floating Ball Valves

On the other hand, floating ball valves utilize a ball that is not fixed but instead floats between two seats. The ball moves in response to the pressure of the fluid, ensuring a tight seal and effective operation. This design is simpler and generally more cost-effective for smaller applications.

Advantages of Floating Ball Valves

• Lower initial cost compared to trunnion ball valves.
• Simpler design, leading to easier repairs and maintenance.
• Good sealing capability for smaller diameters and lower-pressure applications.

Choosing the Right Valve

Ultimately, the choice between a trunnion ball valve and a floating ball valve will depend on your specific application requirements. If your system involves high pressure and flow rates, a Trunnion Vs Floating Ball Valve comparison shows that the trunnion design may be the better option. However, for smaller or less demanding applications, a floating ball valve could be more suitable.

It is essential to work with reputable manufacturers and suppliers to ensure you are receiving high-quality products that fulfill your needs. Companies like Xiangyu not only provide reliable valves but also valuable insights to help you make an educated choice.
