A fully welded ball valve is characterized by its construction, where the valve body, seat, and ball are joined into a single unit through welding. This design enhances the valve's strength and sealing performance, ensuring stable operation under harsh conditions such as high pressure and temperature. Fully welded ball valves are widely used in industries like oil, chemicals, and natural gas, making them essential equipment in these sectors.
● Compact Structure: The fully welded integral ball valve features an integrated design that reduces the number of connection components, resulting in a more compact and space-efficient structure. This design not only simplifies installation and maintenance but also enhances sealing performance.
● Excellent Sealing Performance: The welding connection eliminates potential leakage issues associated with traditional connections, ensuring the stable flow of the medium within the pipeline.
● Strong Corrosion Resistance: The ball valve's main body is typically constructed from corrosion-resistant materials such as stainless steel, effectively combating erosion from various corrosive media and prolonging 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 valve is distinguished by several key features. To begin with, its robust structure ensures long-term durability and reliability, capable of withstanding the most challenging industrial environments. Additionally, the implementation of seamless welding technology eliminates potential leakage points, thereby enhancing safety and performance. Finally, our dedication to quality and innovation guarantees that the valve adheres to the latest industry standards, maximizing the value of your investment.
