In each industrial system, controlling the flow of fluids and gases is one of the most important jobs. A safe, reliable and strong valve makes all the difference. Among many types of valves available today, the top entry trunnion mounted ball valve stands out as one of the most trusted. It combines a durable design with easy maintenance and excellent sealing performance. This API 6D top entry ball valve is widely used in oil, gas, petrochemical and other industries where safety and efficiency are important.

Trunnion Mounted Ball Valve Working Principle

The top entry is a special function principle in the top entry trunnion mounted ball valve. Inside the valve, there is a ball with a hole through its center. When the hole lines up with the pipe, the fluid flows freely. When the ball rotates 90 degrees, the flow stops completely.

What makes this valve different is the trunnion mounted ball valve design. Instead of giving the ball “float”, the ball is placed up and down by the top and down by Tronions. This design reduces stress on valve seats and ensures a tight seal even under high pressure. Because the ball is fixed, the Trunnion-mounted design can handle larger sizes and higher pressures than the floating ball valve.

The “top entry” part of the design means maintenance is easy. The cast steel top entry ball valve can remove the bonnet and reach the ball, seats and seals without removing the entire valve from the pipeline. It saves time, reduces labour, and simplifies repair.

Leak-proof & Durable Trunnion Ball Valve is available

The top entry trunnion mounted ball valve is designed for strong and safe flow control. It works well in the oil, gas and chemical industries and is finalised.

Main advantage

This valve has a top-entry design, which makes it very easy to maintain. Workers can change parts in just 15 minutes without removing the valve from the pipe. It also has a double block and bleed system (DBB) certified by API 6D. This prevents leaks and makes maintenance safe. Because it is built with a cast body, it is cheaper by up to 40% than the lattice valve, but still handles high pressure up to class 600 lb.

Industry benefits

In oil fields, this valve has a 90%cut in maintenance downtime, which saves time and money. In chemical plants, its CF8M steel body with tungsten coating gives it three times more life against war. In city gas lines, the DBB design certified by N331 prevents design leaks and preserves the system.

Top Entry Trunnion Mounted Ball Valve’s key features

The top entry Trunnion Mounted Ball Valve comes with several impressive characteristics that make it valuable in important industries. One of its major features is its tight sealing system. Double block and bleed ball valve ensures frequent pressure on seats, causing zero leakage.

Another feature is its easy maintenance. Since it has a top entry structure, engineers can serve the valve while it is still installed in the pipeline. It makes it highly convenient in large plants where the valve is difficult and expensive.

The valve is also known for its fire-safe and anti-static design. In the case of fire, the valve still shifts the ball against a metal seat and provides sealing. The anti-static system discharges static electricity, prevents sparks and reduces the risk of explosions.

The valve is durable and long-lasting. Its design can handle excessive pressure, temperature change and corrosive environments. With reliable operations and a long service life, it provides strong performance in demand for applications.

Benefits of using Trunnion Mounted Ball Valve

There are many benefits of choosing a top entry trunnion mounted ball valve for industrial systems. 

• The design provides excellent sealing performance. Even under high-pressure conditions, the valve prevents leakage, which ensures safety and efficiency.
• Another benefit is easy operation. Because the ball is supported by the trunnion, the torque required to operate the valve is low. This means that it requires less effort to open or close it, which is particularly helpful for large valves.
• Top entry valve for oil and gas pipelines is another major benefit. Maintenance can be done quickly without removing the valve from the pipeline. It reduces downtime and keeps the production run smooth.
• These valves also provide long service life. They are made with top materials and can withstand warm steam to aggressive chemicals, and can withstand excessive working conditions. 
• They are also versatile, which makes them suitable for oil, gas, water, power plants and many other applications.

Materials Used for Durable Trunnion Mounted Ball Valve

The strength and performance of the top entry trunnion mounted ball valve depend a lot on the materials used in the construction. 

The valve body is usually made of cast steel or forged steel, providing excellent durability and resistance to pressure and temperature changes.

Stainless steel is often used to make a ball valve. This substance guarantees a smooth surface that reduces friction and facilitates a dense seal. PTFE, Nylon or other condition polymers that offer better wear and chemical stability are usually used to make seats.

Non-metal components are included in metal seats for fire-resistant designs to maintain sealing even after heat damage. To guarantee safety and prevent leaks, the valve strain and the sealing of strong, corrosion-resistant materials are also made.

These materials are used by manufacturers to make valves that can withstand tough conditions, resist rust and provide permanent functionality. The top entry trunnion mounted ball valve is a dependable choice for heavy-duty industries thanks to its top entry.

Common application in various industries

The top entry Trunnion mounted ball valve is used widely in industries due to its strength and safety. It is crucial for managing the flow of natural gas, crude oil, and advanced products in the oil and gas sector. Security in high-risk settings, such as pipelines and offshore platforms, is guaranteed by its leak-proof construction.

To manage harsh chemicals, valves are used in the petrochemical and chemical industries.

 Strong material and sealing design prevent rust and leakage while keeping the design operation safe.

In power plants, these valves help control steam, cold water and other liquids. His ability to handle high temperatures and pressure makes them ideal for this region.

They are also used in water treatment plants, pharmaceutical industries and production facilities. 

Think about when choosing a first-class ball valve

It is important to choose the right top entry trunnion mounted ball valve to ensure safe and efficient operation. 

• When choosing -mounted premium quality ball valve, you should first consider the work status. Think about the pressure, temperature and type of liquid the valve will handle.
• Pay attention to the material. Make sure the body, ball, seats and stems are made of materials that can withstand the working environment in the system.
• Pay attention to the material. Make sure the body, ball, seats and stems are made of materials that can withstand the working environment in the system. For corrosive fluids, stainless steel or a special coating may be necessary.
• It is also important to confirm standards and certificates. High pressure trunnion mounted ball valve follows international standards such as ISO, ANSI and API. This guarantees that they are reliable, safe and undergo performance tests.
• Think of the provider’s reputation. Buying from a well-known manufacturer ensures that the valve has undergone a comprehensive test and design.
