Exploring the Benefits of Trunnion Mounted Ball Valves.

Trunnion mounted ball valves (TMBV) are designed with a trunnion mounted ball that is supported by two lower bearings and an upper bearing. In this design, the ball does not touch the body of the valve, which helps to reduce wear and tear. These types of valves have become increasingly popular in the oil and gas industry due to their numerous advantages.

In this article, we will explore the benefits of trunnion mounted ball valves:

1. Increased durability.

One of the main advantages of TMBVs is their increased durability. The trunnion mounted ball design helps to reduce the wear and tear on the valve components, which in turn extends the valve’s lifespan and reduces maintenance costs.

2. Improved reliability.

TMBVs are highly reliable due to their trunnion-mounted design. The ball is supported by two lower bearings and an upper bearing, which ensures that it remains in the correct position and does not become misaligned or stuck.

3. Enhanced sealing.

TMBVs feature a unique sealing system that helps to prevent leaks. The body of the valve is designed to provide a tight seal around the ball, while the upper and lower stem seals help to prevent leakage from around the stem.

4. Reduced torque.

The trunnion mounted ball design helps to reduce the amount of torque required to operate the valve. This is because the ball is supported by the trunnion bearings, which reduces the friction between the ball and body of the valve.

5. Increased flow capacity.

TMBVs have a larger flow capacity compared to traditional floating ball valves. This is because the trunnion mounted ball design allows for a larger ball and seat design, which allows for greater flow capacity.

6. Improved safety.

TMBVs are designed with a built-in safety feature that helps to prevent over-pressurization. If the pressure in the valve exceeds the set limit, the valve will automatically release pressure through a built-in relief mechanism.

7. Easier maintenance.

TMBVs are designed with easy maintenance in mind. The trunnion mounted ball design allows for quick and easy disassembly and reassembly of the valve, which reduces downtime during maintenance.

8. Versatility.

TMBVs are suitable for a wide range of applications. They are commonly used in the oil and gas industry, as well as in the chemical, petrochemical, and power generation industries.

In conclusion, trunnion mounted ball valves offer numerous advantages over traditional floating ball valves. Their increased durability, reliability, sealing, reduced torque, increased flow capacity, built-in safety feature, easier maintenance, and versatility make them an excellent choice for a wide range of applications. If you are looking for a valve that can provide superior performance and longevity, consider the benefits of trunnion mounted ball valves.
