What is a Trunnion Mounted Ball Valve Used For?

A trunnion mounted ball valve is a type of valve used in various industries to control the flow of fluids or gases. It is designed with a hollow ball, which has a hole or port in the center. This ball is attached to a stem at the bottom and supported by trunnions, or shafts, at the top and bottom. The rotation of the stem allows the ball to open or close, controlling the flow through the valve.

The trunnion mounted ball valve is commonly used in the oil and gas industry, as well as in chemical plants, power plants, and other industrial applications. Its unique design and features make it suitable for a wide range of applications where high pressure, high temperature, or corrosive fluids are involved.

High Pressure Applications.

One of the primary uses of a trunnion mounted ball valve is in high-pressure applications. These valves are specifically designed to withstand extreme pressures that would typically cause other types of valves to fail. The trunnions provide additional support to the ball, preventing it from being pushed out of place by the pressure. This ensures the valve remains operational, even under high-pressure conditions.

High Temperature Applications.

In addition to high-pressure applications, trunnion mounted ball valves are also used in high-temperature environments. The materials used in the construction of these valves can withstand extreme temperatures, making them suitable for applications where conventional valves would not be able to withstand the heat. The trunnion design helps to distribute the stress evenly, preventing warping or damage to the valve when exposed to high temperatures.

Corrosive Fluids.

Trunnion mounted ball valves are also commonly used in industries where corrosive fluids are present. These valves are made from materials that are resistant to corrosion, such as stainless steel or exotic alloys, ensuring they can withstand the aggressive nature of these fluids. Additionally, the trunnion design helps to protect the valve by reducing contact between the ball and the valve body, minimizing the risk of corrosion or damage.

Other Applications.

Trunnion mounted ball valves also find applications in various other industries and processes. They are used in wastewater treatment plants, where they can handle the flow of fluids containing solids and debris without clogging or obstructing the valve. They are also used in mining operations to control the flow of slurry, a mixture of water and solid particles.

Furthermore, trunnion mounted ball valves are used in natural gas transportation and distribution systems. These valves ensure the safe and efficient flow of natural gas through pipelines, helping to regulate the pressure and prevent leaks. The trunnion design ensures the valve remains reliable and operational, even under the demanding conditions experienced in the natural gas industry.

Conclusion.

Trunnion mounted ball valves are versatile valves used in a wide range of industries and applications. They are specifically designed for high-pressure, high-temperature, and corrosive fluid environments. Their unique trunnion design provides additional support to the ball, making them highly reliable and durable. Whether it is in the oil and gas industry, chemical plants, power plants, or wastewater treatment plants, trunnion mounted ball valves ensure efficient flow control and contribute to the safe operation of various processes.
