Trunnion Mounted Ball Valve: Ensuring Reliable Performance in High-Pressure Applications

Trunnion mounted ball valves are critical components in various industrial applications, especially where high-pressure handling and operational efficiency are paramount. These valves are distinguished by their robust design, which includes a trunnion—a stationary support element that holds the ball in place—making them ideal for controlling the flow of liquids and gases in demanding environments. This article explores the design, functionality, and applications of trunnion mounted ball valves, emphasizing their advantages and key considerations in their selection.

Design and Construction A trunnion mounted ball valve is characterized by its unique design, where the ball is fixed in place by a trunnion, rather than being free to float as in a standard floating ball valve. The trunnion is a cylindrical shaft that is an integral part of the ball and is anchored to the valve body. This design ensures that the ball remains in position, regardless of the pressure exerted by the flow medium, reducing the torque required to operate the valve and allowing for more consistent sealing performance.

Components:

Ball: The ball is the primary component that controls the flow of the medium. In a trunnion mounted design, the ball is securely anchored by the trunnion, which minimizes movement and ensures stability even under high pressure.

Trunnion: The trunnion is a fixed shaft that holds the ball in place. It is connected to the valve body and provides support, allowing the ball to rotate without moving axially. This design reduces the stress on the valve seats and helps maintain a tight seal.

Seats: Trunnion mounted ball valves typically use spring-loaded or piston-type seats. These seats are designed to move slightly against the ball, ensuring a tight seal. The spring or piston compensates for wear, pressure fluctuations, and temperature changes, thereby enhancing the valve’s longevity and reliability.

Stem: The stem connects the actuator or manual control handle to the ball. In a trunnion mounted design, the stem is isolated from the ball, reducing the operational torque and making it easier to operate the valve, especially in large-diameter applications.

Body: The body of a trunnion mounted ball valve is typically constructed from robust materials such as stainless steel, carbon steel, or alloy steel. The choice of material depends on the application and the type of fluid being controlled.

Functionality and Operation The primary function of a trunnion mounted ball valve is to start, stop, or regulate the flow of a medium through a pipeline. When the valve is in the open position, the bore (or port) of the ball aligns with the pipeline, allowing free flow. When rotated 90 degrees, the ball’s solid part blocks the flow, effectively sealing the pipeline.

The trunnion mounted design offers several operational advantages:

Low Torque Operation: Due to the fixed position of the ball, trunnion mounted ball valves require significantly less torque to operate compared to floating ball valves. This feature is particularly beneficial in large-diameter valves or high-pressure systems, where operating torque can be a limiting factor.

Bidirectional Sealing: These valves can provide a tight seal in both directions, making them suitable for applications where flow reversal is a concern. The spring-loaded seats ensure that the valve remains sealed even when there is low or no pressure on the downstream side.

Pressure Relief: In high-pressure applications, excess pressure can build up in the valve body. Trunnion mounted ball valves often include an automatic pressure relief feature that vents excess pressure, ensuring safe operation and preventing damage to the valve or system.

Applications Trunnion mounted ball valves are widely used in industries where reliable flow control under high pressure is essential. Some of the key industries and applications include:

Oil and Gas: These valves are extensively used in the upstream, midstream, and downstream sectors of the oil and gas industry. They are commonly found in pipelines, storage facilities, and processing plants, where they manage the flow of crude oil, natural gas, and refined products.

Petrochemical: In petrochemical plants, trunnion mounted ball valves are used to control the flow of chemicals, gases, and other process fluids. Their ability to handle high pressures and aggressive media makes them suitable for such demanding applications.

Power Generation: In power plants, these valves are employed in steam and cooling systems, where they ensure precise flow control under high pressure and temperature conditions.

Water Treatment: Trunnion mounted ball valves are also used in water treatment facilities, particularly in high-pressure applications such as reverse osmosis systems and high-pressure pump systems.

Chemical Processing: The chemical industry often deals with corrosive and hazardous substances. Trunnion mounted ball valves, constructed from corrosion-resistant materials, ensure safe and reliable operation in such environments.

Advantages of Trunnion Mounted Ball Valves Trunnion mounted ball valves offer several advantages over other types of valves, making them a preferred choice in many high-pressure applications:

Enhanced Durability: The trunnion design reduces wear and tear on the ball and seats, leading to a longer service life.

Lower Operational Cost: The low torque requirement means that smaller, less expensive actuators can be used, reducing overall operational costs.

High Pressure Handling: These valves are specifically designed to handle high-pressure applications, providing reliable sealing and operation even in the most demanding environments.

Safety Features: The inclusion of pressure relief mechanisms and the ability to provide a tight seal in both directions enhance the safety and reliability of the system.

Versatility: Trunnion mounted ball valves can be used in a wide range of applications, from oil and gas to water treatment, making them a versatile choice for various industries.

Key Considerations for Selection When selecting a trunnion mounted ball valve, several factors should be considered to ensure optimal performance:

Material Compatibility: The valve materials should be compatible with the media being handled. For corrosive or aggressive media, valves made from stainless steel or other corrosion-resistant materials are recommended.

Pressure Rating: The valve’s pressure rating must match or exceed the system’s operating pressure to ensure safe and reliable performance.

Size and Bore: The size of the valve and the bore size should be appropriate for the application to ensure efficient flow control.

Temperature Range: The valve should be capable of operating within the system’s temperature range without compromising its performance or integrity.

Conclusion Trunnion mounted ball valves are an essential component in industries that require precise and reliable flow control under high-pressure conditions. Their robust design, combined with the ability to handle bidirectional flow and relieve excess pressure, makes them ideal for demanding applications. When selecting a trunnion mounted ball valve, it is crucial to consider factors such as material compatibility, pressure rating, and size to ensure optimal performance.

What is a Trunnion Mounted Ball Valve?

A trunnion mounted ball valve is a type of valve that uses a ball as a sealing element. The ball is held in place by two trunnions, or short cylinders, attached to the valve's body. The ball is usually made of metal but can also be made of other materials, such as plastic.

The main advantage of a trunnion mounted ball valve over other valves is that it is much easier to operate. When the handle is turned, the ball rotates on its axis and either opens or closes the valve. This means that there is no need to lift or lower the ball, which can be difficult with some other types of valves.

Trunnion mounted ball valves are versatile and can be used in various applications. They are commonly used in oil and gas pipelines, as well as in chemical and petrochemical plants.

It may be the perfect choice for your next project to use a trunnion mounted ball valve, which is reliable and easy to operate.

What is the working principle of a ball valve mounted on a trunnion?

A ball is used as the sealing element in a trunnion mounted ball valve. Two trunnions, or short cylinders, are attached to the valve's body to hold the ball. Fluid flows through the ball when the valve is in the open position. This allows fluid to flow freely through the valve. When the valve is in the closed position, the ball is turned so that it is perpendicular to the flow of fluid. This blocks off the fluid flow and prevents it from passing through the valve.

Various benefits of a Trunnion Mounted Ball Valve

A trunnion mounted ball valve has many advantages over other types of valves. One advantage is that it is much easier to operate. Trunnion mounted ball valves are versatile and can be used in various applications.

Another advantage of a trunnion mounted ball valve is that it is less likely to leak than other valves. This is because two trunnions hold the ball in place, which creates a tight seal. Trunnion mounted ball valves are also less likely to jam than other valves.

 Yet another advantage of a Trunnion Mounted Ball Valve is that they require less maintenance than other types of valves due to their design, which eliminates many potential problem areas. 

A final advantage of Trunnion Mounted Ball Valves is that they have a long lifespan and can withstand harsh conditions better than other valves.

Why Use a Trunnion Mounted Ball Valve?

For various reasons, a trunnion mounted ball valve might be preferred over another type of valve. One reason is that they are much easier to operate. Trunnion mounted ball valves are versatile and can be used in various applications. Another reason trunnion mounted ball valves are a good choice is that they are less likely to leak or jam and require less maintenance. Finally, trunnion mounted ball valves have a very long lifespan and can withstand harsh conditions better than other valves.

When Not to Use a Trunnion Mounted Ball Valve

There are a few situations when using a trunnion mounted ball valve is not ideal. One example is when there is a need for frequent valve operation, as the trunnions can wear down over time with repeated use. Another situation where a different type of valve might be better suited is when very high pressures are involved, as the ball in a trunnion mounted ball valve could be forced out of alignment and cause a leak. Additionally, if precise control over fluid flow is required, another type of valve would likely provide more accurate results.

Exploring the Different Types of Ball Valves and Their Applications

Ball valves are mechanical devices used to regulate the flow of fluids within a system by means of a spherical disc or "ball" contained within the valve body. The ball has a hole or port through its center, allowing fluid to pass through when aligned with the flow path and stopping the flow when rotated perpendicular to it. This simple yet effective design makes ball valves versatile and widely used in various industries for controlling the movement of liquids or gases.

The operation of ball valves is typically controlled by a lever, handle, or actuator, which rotates the ball within the valve body to open, close, or regulate the flow. This rotational motion offers quick and reliable shutoff, making ball valves suitable for applications where tight shut-off is required to prevent leakage or to control the flow rate precisely.

Ball valves are fundamental components in fluid control systems, offering efficient shut-off capabilities and reliable performance across a wide range of applications in industries such as oil and gas, petrochemical, water treatment, power generation, and more. Their simple yet effective design, coupled with their versatility and durability, makes them indispensable in modern engineering and industrial processes.

Types of Ball Valves There are several types of ball valves, each designed to meet specific requirements and operating conditions. Here are some common types:

Floating Ball Valves: Floating ball valves are a type of ball valve where the ball is not fixed in place but instead floats between the valve seats. Here's a more detailed explanation:

Description: Floating ball valves consist of a spherical ball with a hole through its center, housed within a valve body. The ball is held in position by the valve seats, which are typically made of soft materials like PTFE (polytetrafluoroethylene) or elastomers. When the valve is in the closed position, the pressure of the fluid forces the ball against the downstream seat, creating a seal and preventing flow through the valve. In the open position, the ball rotates to align the hole with the flow path, allowing fluid to pass through.

Operation: The operation of floating ball valves is relatively simple. When the valve handle or actuator is turned to the closed position, the ball is pushed by the fluid pressure against the downstream seat, creating a seal and stopping the flow of fluid. Conversely, when the valve is opened, the ball rotates within the valve body to align the hole with the flow path, allowing fluid to pass through.

Advantages:

Simple design: Floating ball valves have a straightforward design, making them easy to manufacture, install, and maintain. Cost-effective: Compared to other types of ball valves, floating ball valves are often more affordable, making them a popular choice for general industrial applications. Suitable for low to moderate pressure applications: Floating ball valves perform well in applications where the pressure requirements are not extremely high.

Disadvantages:

Less effective sealing at high pressures: Floating ball valves may experience reduced sealing effectiveness at higher pressures compared to other types of ball valves like trunnion-mounted ball valves. Limited to smaller sizes: Floating ball valves are typically used in smaller sizes and may not be suitable for larger pipe diameters or higher flow rates.

Trunnion Ball Valves: Trunnion ball valves are a type of ball valve designed to handle high-pressure and high-flow applications. Here's a detailed overview of trunnion ball valves:

Description: Trunnion ball valves feature a fixed ball supported by trunnion bearings or pins at the top and bottom of the ball. Unlike floating ball valves, where the ball is free to move within the valve body, the trunnion-mounted ball remains stationary and is supported by the trunnion mechanism. This design provides additional support and stability, allowing the valve to handle higher pressures and larger pipe sizes with greater reliability.

Operation: Trunnion ball valves operate similarly to other types of ball valves. When the valve is in the closed position, the ball is pressed against the downstream seat by the fluid pressure, creating a tight seal and preventing flow through the valve. To open the valve, the ball rotates within the valve body to align the hole with the flow path, allowing fluid to pass through.

Advantages:

Excellent sealing performance: The trunnion-mounted ball design ensures superior sealing performance, even under high-pressure conditions, compared to floating ball valves. Suitable for high-pressure and high-flow applications: Trunnion ball valves are well-suited for applications where the operating pressures and flow rates are substantial. Reduced operating torque: The trunnion-mounted ball design reduces the operating torque required to operate the valve, making it easier to open and close, particularly in larger sizes.

Disadvantages:

Higher initial cost: Trunnion ball valves typically have a higher initial cost compared to floating ball valves due to their more complex design and construction. Limited flexibility: Trunnion ball valves may not be as versatile as floating ball valves and may not be suitable for low-pressure or smaller-sized applications.

Top-Entry Ball Valves: Top-entry ball valves are a specific type of ball valve designed with accessibility and maintenance in mind. Here's a comprehensive overview:

Description: Top-entry ball valves feature a design where the valve body can be disassembled from the top, allowing easy access to internal components such as the ball, seats, and stem. This design enables maintenance and repair work to be carried out without removing the valve from the pipeline, making it convenient and cost-effective.

Operation: The operation of top-entry ball valves is similar to other types of ball valves. The ball within the valve body rotates to control the flow of fluid, with the valve opening and closing by aligning or misaligning the hole in the ball with the flow path.
