Floating ball valves have a ball that floats within the valve. When the valve is closed, the ball is pressed against the seat by the pressure of the fluid inside the valve. This design creates a tight seal and allows for efficient operation.
Trunnion ball valves feature a ball that is fixed in place by supports above and below. They are designed for high-pressure applications and offer a more stable operation when the pressure fluctuates.
Floating ball valves excel in smaller pipe sizes and lower pressure systems. They are often easier to install and maintain, leading to reduced overall costs. Additionally, their ability to handle varying flow rates makes them a flexible option in many applications.
Trunnion ball valves are well-suited for high-pressure applications and larger pipe sizes. They provide excellent control over flow and pressure, making them ideal for industrial use. Their design minimizes wear on the seats, leading to longer service life.
Generally, floating ball valves are easier to maintain, as they have fewer parts and simpler designs. This results in lower maintenance costs. In contrast, trunnion ball valves can be more expensive upfront, but may provide long-term savings in high-pressure environments due to their durability.
If you are working with smaller pipelines, lower pressure systems, or require a valve that is easy to maintain, a floating ball valve is typically the better choice. They are versatile and cost-effective for many applications.
For high-pressure applications or larger pipelines, a trunnion ball valve offers more stability and control. If your project requires precise flow control and higher durability, investing in a trunnion ball valve would be beneficial.
