Trunnion Ball Valve vs Floating Ball Valve: A Comprehensive Comparison

When it comes to industrial piping systems, selecting the right valve is crucial for ensuring efficient operation and safety. Among various types of valves, Trunnion Ball Valves and Floating Ball Valves are two prominent options, each with its unique features and applications.

Understanding Trunnion Ball Valves

Trunnion Ball Valves are designed with a ball that is supported by trunnions on both the top and bottom. This construction provides excellent stability and makes the valve suitable for high-pressure applications. The trunnion support minimizes ball movement, ensuring a tight seal even under demanding conditions.

Exploring Floating Ball Valves

In contrast, Floating Ball Valves operate differently as the ball is not fixed on a trunnion. Instead, the ball 'floats' and is held in place by the valve seats. This design allows for a simple mechanism, making it easier to manufacture and maintain. Floating Ball Valves are typically used in lower-pressure systems where ease of operation is a priority.

Key Differences

While both types of valves serve the purpose of controlling fluid flow, there are distinct differences to consider:

• Pressure Rating: Trunnion Ball Valves are better suited for high-pressure applications, whereas Floating Ball Valves are ideal for lower-pressure situations.
• Design Complexity: The design of Trunnion Ball Valves is more complex due to the trunnion support, whereas Floating Ball Valves have a simpler construction.
• Maintenance: Floating Ball Valves generally require less maintenance, making them a popular choice for facilities with limited maintenance resources.

Ultimately, the choice between Trunnion Ball Valves and Floating Ball Valves depends on specific operational requirements. Factors such as pressure, fluid type, and maintenance capabilities should guide the selection process.
