The fully welded ball valve is known for its clever structural design, which uses advanced welding technology to integrate the valve body, valve seat, and ball into one unit. This design not only significantly improves the strength and sealing performance of the valve, but also ensures stable operation under extreme conditions such as high pressure and high temperature. Due to its excellent performance, fully welded ball valves have been widely used in industries such as petroleum, chemical, and natural gas, becoming an important component of these industries.
● Compact Structure: The fully welded integral ball valve adopts an integrated design, reducing the number of connecting components, making the structure more compact and space saving. This design not only simplifies installation and maintenance, but also improves sealing performance.
● Excellent Sealing Performance: Welding connections eliminate common leakage problems in traditional connections, ensuring stable flow of media inside the pipeline.
● Strong Corrosion Resistance: The main body of the ball valve is usually made of corrosion-resistant materials such as stainless steel, which effectively resists erosion caused by various corrosive media and extends its 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-term durability and reliability, capable of withstanding the harshest industrial conditions. Secondly, the use of seamless welding technology effectively eliminates potential leakage points, enhancing safety and overall performance. Lastly, our commitment to quality and innovation ensures that our valves meet the latest industry standards, maximizing your investment value.
