As industries continually grow, the type of equipment and technology used for different applications is constantly evolving. One of the tools that are used in various industries, especially in the oil and gas sector, is the ball valve. The valve is essential to the process of isolating or controlling the flow of different fluids. One kind of valve that has been gaining ground in recent times is the Flanged Trunnion Mounted Ball Valve. This valve has several unique features that make it stand out from other types of valves. In this article, we will explore all the essential aspects of this valve and why it is widely used.
What is a Flanged Trunnion Mounted Ball Valve?
A Flanged Trunnion Mounted Ball Valve is a high-performance valve that is designed to handle more demanding applications. It is an example of a quarter-turn valve. This valve has a metallic or soft seat and is suitable for some of the toughest conditions, including high-temperature and high-pressure applications. The Flanged Trunnion Mounted Ball Valve is mounted on two trunnions that permit it to pivot and produce a low torque necessary for long-term reliability.
This valve consists of a two-piece or three-piece body that is bolted or clamped together. The body has drilled or threaded flange connections to fit with the piping systems. Flanged trunnion mounted ball valves are constructed from different materials, including brass, stainless steel, carbon steel, chrome, and monel, among others.
Design of the Flanged Trunnion Mounted Ball Valve.
The design of the Flanged Trunnion Mounted Ball Valve is such that it can withstand extreme temperatures and pressure conditions. It accomplishes this through various design choices, such as the trunnion system. As mentioned earlier, the valve sits on two trunnions, which allow it to pivot and reduce the torque required to operate it. This trunnion design means that it is impossible for the valve to dislodge or shift in operation.
The body of the Flanged Trunnion Mounted Ball Valve is a two-piece or three-piece design. The two-piece design separates the valve body into separate pieces, allowing for ease of maintenance. The three-piece design has two end caps that seal the valve. The middle section accommodates the ball, stem, and seats. One of the benefits of the three-piece design is that it makes it possible for in-line maintenance.
Additionally, the Flanged Trunnion Mounted Ball Valve has a full bore or reduced bore design. In the full bore design, the ball is the same size as the pipeline. On the other hand, the reduced bore design has a ball that is one size smaller than the pipeline, leading to a reduced flow area. The reduced bore design is more cost-effective and takes up less space It is essential to consider the sizing of the ball concerning the pipeline, as the smaller the ball is, the higher the velocity of the flow.
Applications of the Flanged Trunnion Mounted Ball Valve.
Flanged Trunnion Mounted Ball Valves are ideal for extreme applications and are utilised in various industries. They are especially useful in high-temperature and high-pressure conditions such as oil and gas, chemical, and petrochemical applications. The valve is also used in industrial processes that involve highly abrasive fluids, including slurries, viscous fluids, and high solid content mixtures.
In the oil and gas industry, the Flanged Trunnion Mounted Ball Valve is used in offshore and onshore applications. It is used for pipeline transportation, compression, and refining. In the chemical industry, it is used in the production of chemicals such as fertilisers, acids, and solvents. It is useful to regulate flow in the production, refining, and transport of these chemicals.
A Flanged Trunnion Mounted Ball Valve is also used in other industries, including food and beverage, pharmaceuticals, pulp and paper, and power generation.
Conclusion.
In conclusion, the Flanged Trunnion Mounted Ball Valve is a highly versatile valve that is used in various industries. Its unique design makes it suitable for extreme applications and ensures long-term reliability. The trunnion design makes it impossible for the valve to shift or become dislodged during operation. The two-piece and three-piece designs allow for ease of maintenance, while the full bore and reduced bore designs allow for flexibility. With its wide application, the Flanged Trunnion Mounted Ball Valve is a testament to the essentiality of innovation in equipment design.
