Forged trunnion ball valves are a popular type of valve used in various industries such as oil and gas, petrochemical, and power generation.

These valves are designed to regulate the flow of various fluids like gas, oil, water, and steam, among others. They are preferred over other types of valves due to their durability, reliability and ability to withstand high pressure and temperature applications.

Forged trunnion ball valves come in various sizes ranging from 2″ to 60″ inches in diameter, with a pressure range of 150 to 2500 LBs.

They are also available in different materials, including carbon steel, stainless steel, and exotic alloys like Duplex and Inconel, to suit different application needs. The design of these valves allows for easy operation with minimal effort, making them user-friendly.

Operators can be manual, pneumatic, hydraulic, or electric. Manual operators are commonly used for low-pressure applications, while pneumatic, hydraulic, and electric operators are used for high-pressure applications, where valve control is difficult manually.

These valves have a trunnion, which is a fixed shaft that supports the ball at both ends, ensuring that it stays in place and rotates smoothly, reducing wear and tear on the seals. The ball rotates 90 degrees to open or close the valve, allowing flow in one direction only. This design makes trunnion ball valves reliable and virtually maintenance-free, providing a long service life.

Forged trunnion ball valves are used in various applications, including pipeline transportation, oil and gas processing, power generation, and chemical and petrochemical industries, among others. They are used in different processes, such as isolation, control and regulation, or protection, depending on the application requirements.

In conclusion, the benefits of forged trunnion ball valves are wide-ranging, from their ability to withstand high-pressure applications to their ease of operation and long service life. Their availability in different sizes and materials, coupled with various operators to choose from, makes them an ideal solution for various industries and applications.

3E Engineering manufactures in general trunnion ball valve of casting steel and stainless steel body,however,if required by customers,forged carbon steel and stainless steel and others special.

forged materials are available,of which the flange dimensions and face to face dimensions are the same as that of casting trunnion ball valves.

Except for full bore ball valves,3E Engineering also supply ball valves with reduced bore to meet different of customers requirements,which not only lowers the cost and pricing,but also satisfies the special requirement of customers.
