What is a trunnion mounted ball valve

In modern industry, applying various valves is crucial, especially valves used to control the flow of fluids. A trunnion-mounted ball valve is a popular type of valve that is widely used in many fields due to its unique design and superior performance. This article will explore the basic structure, the working principle, and the main uses of trunnion mounted ball valves in depth, let us unveil the mystery of this industrial equipment together.

I. Basic structure of a trunnion mounted ball valve

The design features of trunnion mounted ball valves make it significantly different from traditional floating ball valves. The core component of this valve is a ball with a support rod. The ball is fixed to the upper and lower parts of the valve by support, forming a stable support system. Specifically, the main body of the valve consists of the valve body, valve ball, valve seat, and drive device.

1. Valve body: As the external structure of the entire valve, the valve body is usually made of high-strength materials to withstand high temperatures and high-pressure working environments.

2. Valve ball: As the control element of the fluid passage, the ball is often provided with a perforation inside, which controls the flow of the fluid by rotation.

3. Valve seat: Generally made of wear-resistant and high-temperature resistant materials, it provides good sealing performance and ensures that the fluid does not leak through non-designed paths.

4. Drive device: It can be manual, pneumatic, or electric, and can be selected according to actual needs. Such diversity enables the trunnion mounted ball valve to adapt to different operating environments.

II. Working principle of a trunnion mounted ball valve

The working principle of trunnion mounted ball valve is relatively simple and intuitive. Its basic operation is to open or close the fluid channel by rotating the valve ball. When the valve ball rotates 90 degrees, the fluid medium can pass through the valve smoothly; when the valve ball rotates back to the closed position, the fluid flow is completely blocked.

The advantage of this design is that the valve body support structure effectively shares the weight of the valve ball, reduces the wear of the valve stem, and ensures better sealing and flow characteristics. In addition, the sealing system of the trunnion mounted ball valve usually adopts a double sealing design, which not only improves its safety but also effectively reduces the risk of leakage.

III. Application fields of a trunnion mounted ball valve

Trunnion mounted ball valves are widely used in many industrial fields. In the oil and gas industry, they are used to control the flow of crude oil and natural gas; in the chemical industry, valves can effectively control the transportation safety of various chemical media; in the power industry, trunnion mounted ball valve is used for the flow control of cooling water and steam.

In addition, in the field of municipal water supply and drainage, valves also show their superior performance, ensuring the efficient use and safe transportation of water resources.

IV. Why choose a trunnion mounted ball valve?

There are many reasons for choosing the trunnion mounted ball valve. First, as mentioned above, the valve has extremely high sealing and low leakage rate, which can meet strict environmental protection and safety requirements. Secondly, the wear resistance and corrosion resistance of the valve make it perform well in high-intensity industrial environments and extend the service life of the equipment.

In addition, the maintenance of a trunnion mounted ball valve is relatively simple, and it does not require frequent maintenance and replacement, which reduces operating costs. It is worth mentioning that with the continuous advancement of technology, modern trunnion mounted ball valve can also integrate intelligent monitoring systems to track the operating status of the valve in real time, improving the flexibility and safety of use.

V. Summary

In general, the trunnion mounted ball valve has won wide applications with its unique design and excellent performance. This valve provides important support for fluid control in various industries with its stable working characteristics and reliable sealing ability. With the development of industrial automation and intelligence, the application prospects of trunnion mounted ball valves will be broader. In the face of increasingly stringent engineering requirements, choosing a high-quality trunnion mounted ball valve is undoubtedly a wise move to ensure process safety and efficiency. Whether in the planning of new projects or the upgrading and transformation of existing equipment,the trunnion mounted ball valve will be a trustworthy choice to help the sustainable development of various industries.
