Fully Welded Ball Valve

Full welded ball valve will be no external leakage.Ball is highly pecision processed.Advanced computer detector tracks and detects the process of ball processing. Stress would not be uneven since the body material is the same with the pipe material.

Product Description

Main Features

The Full Welded Ball Valve is a heavy-duty industrial valve designed for use in extreme conditions and high-pressure applications. It features a unique design that utilizes a full-welded body, which allows for the valve to be completely sealed and eliminates the need for gaskets or other seals. The valve is available in different sizes, pressure ratings, and materials of construction to accommodate different flow requirements. The valve can be operated with various actuator like pneumatic, electric, hydraulic etc.

The valve is designed with features such as zero leakage, high-pressure rating, and high-temperature rating, and bi-directional tight shut off. The Full Welded Ball Valve is ideal for use in the oil and gas industry, power generation plants, chemical processing plants, and other industrial applications where zero leakage and complete isolation is required. The forging materials are subjected to ultrasonic examination as per ASME nondestructive flaw detection requirements. The welding slope on the connection face is subected to liquid penetration examination. Buy Ball Valve and get high quality full welded ball valve at a good price, contact us to know more.

Some advantages of the Full Welded Ball Valve include:

1. Zero leakage: The full-welded body design eliminates the need for gaskets or other seals, resulting in zero leakage of the valve which is highly desirable in some industries like oil and gas, chemical processing and power generation.

2. High-pressure rating: The valve is designed to withstand high-pressure and is suitable for use in a wide range of applications such as in the oil and gas industry, power generation plants, and chemical processing plants.

3. High-temperature rating: The valve is also designed to withstand high temperatures, making it suitable for use in high-temperature applications such as furnace and boiler feedwater control and other process where temperature exceeds the limit of traditional valve.

4. Complete isolation: the full-welded body design provides complete isolation and prevents any potential external leaks or contamination to the fluid.

5. Bi-directional tight shut off: the valve provides tight shut off in both directions, ensuring that no leakage occurs when the valve is in closed position.

6. Variety of actuator options: the valve can be operated with various actuators like pneumatic, electric, hydraulic, etc, providing flexibility to the end user.

7. Variety of materials of construction: The valve is available in a wide range of materials of construction such as carbon steel, stainless steel, alloy steel, and other alloy materials to meet different application and process conditions.



The Full Welded Ball Valve is well suited for a variety of industrial applications, including:

1. Oil and Gas Industry: The valve's zero leakage, high-pressure and high-temperature rating make it suitable for use in the oil and gas industry, particularly in harsh environments such as offshore platforms, high-pressure pipelines and other critical locations where the risk of leakage must be minimized.

2. Power Generation: The valve's zero leakage and high-pressure rating make it ideal for use in power generation plants, including nuclear, coal, gas, and renewable energy facilities where high pressure and high temperature are present.

3. Chemical Processing: The valve's zero leakage and high-pressure rating make it suitable for use in chemical processing plants, where it can be used to control the flow of corrosive chemicals and other hazardous materials

4. Pharmaceutical, Food and Beverage and other hygienic process industries: the valve is well suited for use in these hygienic process industry, where the valve need to be designed to meet the stringent standards of hygiene and cleanliness.

5. High-purity process application: where the contamination of fluid should be avoided, the full-welded design of the valve provides a perfect solution.

6. Industrial gas application: the valve's ability to withstand high-pressure and high-temperature, make it well suited for use in industrial gas application, like LNG transfer and other high-pressure gas transfer.


These are just a few examples, the Full Welded Ball Valve can be used in many other industrial settings where flow control is needed in extreme conditions or high-pressure environments, or where zero leakage is a must.
