What is the Main Difference

Fully Welded Ball Valve is a type of valve that has been designed with a welded body. Unlike other valves that have a body joint connecting the valve's body to the end connection, the Fully Welded Ball Valve has no such joint. This design reduces the valve's weight, enhances its serviceability, and makes it easy to handle. As a result, Fully Welded Ball Valves have become increasingly popular in various industries that require high-pressure and high-temperature applications. The valve is, therefore, an essential component in various plants.

What is the working principle of a Fully Welded Ball Valve?

A fully welded ball valve makes use of a highly spherical ball, which rotates in the valve's cavity to start, stop or regulate the fluid flow. When the valve is fully open, the ball is a quarter turn away from a complete turn, which allows for maximum flow through the valve. When it is closed, the ball stops the flow of the fluid by sealing off the valve's channel. The stem that passes through the ball is connected to the actuator, which controls the valve's position.

What are the advantages of using a Fully Welded Ball Valve?

One of the main advantages of using Fully Welded Ball Valves is that they have a reduced weight, which makes them easier to handle and install. Additionally, these valves require less maintenance than most conventional valves since they have fewer components, and they are welded to eliminate the possibility of leaks that are typically found in joints. Also, these valves have the ability to handle high-pressure and high-temperature applications, which makes them ideal in industries that require such conditions.

What are the different types of Fully Welded Ball Valves?

Fully Welded Ball Valves come in various types, including trunnion, floating, and top entry. Trunnion ball valves are available in both two and three-piece designs. They offer increased valve support and stability and are suitable for high-pressure applications. Floating ball valves are characterized by their simplicity and cost-effectiveness, making them ideal for low-pressure applications. Top entry ball valves have a two or three-piece design and are suitable for high-pressure and high-temperature applications.

What are the industries that use Fully Welded Ball Valves?

Fully Welded Ball Valves are used in various industries, including oil and gas, petrochemicals, chemical processing, and power plants. They are particularly recommended for applications where the pipeline operates under high pressure and high temperature.

In conclusion, Fully Welded Ball Valves have numerous advantages over other types of valves. Their reduced weight, easy handling and installation, and low maintenance make them a popular choice in different industries. Manufacturers provide a broad range of fully welded ball valves to satisfy different customer needs in different industries. Hence, if you need a dependable valve for your project, consider purchasing the Fully Welded Ball Valve, and you will not regret it.
