The fully welded ball valve is renowned for its ingenious structural design, which employs advanced welding techniques to ensure a tight fit between the valve body, seat, and ball. This design significantly enhances the valve's strength and sealing performance, allowing it to operate stably even under extreme conditions such as high pressure and high temperature. Thanks to its outstanding performance, the fully welded ball valve has found widespread application in industries like oil, chemical, and natural gas, becoming an essential component in these sectors.
● Compact Structure: The fully welded integral ball valve employs an integrated design, which reduces the number of connecting parts and makes the structure more compact and space-saving. This design not only simplifies installation and maintenance but also enhances the sealing performance.
● Excellent Sealing Performance: Welding connections eliminate common leakage issues associated with traditional connection methods, ensuring the stable flow of media within the pipeline.
● Strong Corrosion Resistance: The main body of the ball valve is typically made from stainless steel and other corrosion-resistant materials, which effectively resist the erosion of various corrosive media and extend the service life.

Q1:What is the main suitable of this valve?
This product is especially suitable for steel, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media.
Q2:What mechanical principle is used?
The mechanical principle of the fully welded ball valve lies in its sophisticated design, which ensures reliable fluid control. The valve features a spherical disc, or ball, with a bore that can be rotated 90 degrees between open and closed positions. When the bore is aligned with the pipeline, fluid flows freely through the valve.
Our fully welded ball valves boast several significant advantages. Firstly, their robust structure ensures long-lasting durability and reliability, capable of withstanding the harshest industrial environments. Secondly, the use of seamless welding technology effectively eliminates potential leakage risks, enhancing safety and overall performance. Lastly, our commitment to quality and innovation ensures that our valves meet the latest industry standards, maximizing your return on investment.
