Why are trunnion mounted ball valves

Trunnion Mounted Ball Valve is a type of valve that utilizes a trunnion mounted design to support the ball. This design allows for increased stability and reduced wear, making it ideal for use in applications where high pressures and temperatures are present. Trunnion Mounted Ball Valves are commonly used in the oil and gas industry, as well as in power plants and chemical processing plants. They are known for their reliability, durability, and ability to handle a wide range of fluids and gases.

What are the benefits of using a Trunnion Mounted Ball Valve?

Trunnion Mounted Ball Valves offer several benefits over other types of valves:

1. Increased stability: The trunnion-mounted design provides increased stability, which helps to reduce wear and tear on the valve components.
2. Improved performance: Trunnion Mounted Ball Valves are able to handle high pressures and temperatures, making them ideal for use in harsh environments.
3. Reduced maintenance: Because they are designed for durability and reliability, Trunnion Mounted Ball Valves require less maintenance than other types of valves.

What are the different types of Trunnion Mounted Ball Valves?

There are several different types of Trunnion Mounted Ball Valves, including:

• Top entry: This type of valve can be serviced without removing it from the pipeline, making it ideal for use in applications where downtime is not an option.
• Side entry: This type of valve is easier to install and remove than top entry valves, but may require more maintenance over time.
• Fully welded: This type of valve is permanently welded to the pipeline, making it ideal for use in applications where leakage is not an option.

What should I consider when selecting a Trunnion Mounted Ball Valve?

When selecting a Trunnion Mounted Ball Valve, it is important to consider:

• The type of fluid or gas being handled
• The operating temperature and pressure
• The size of the valve
• The materials used to construct the valve

In summary, Trunnion Mounted Ball Valves are a reliable and durable option for use in a wide range of applications. When selecting a Trunnion Mounted Ball Valve, it is important to consider factors such as the type of fluid or gas being handled, the operating temperature and pressure, the size of the valve, and the materials used to construct the valve.
