A fully welded ball valve is a valve with a structure that is entirely welded, where the valve body, seat, and ball are welded together to form a single unit. This design not only enhances the valve's strength and sealing performance but also ensures stable operation under harsh conditions such as high pressure and high temperature. Fully welded ball valves are widely used in industries like oil, chemical, and natural gas, serving as critical equipment in these sectors.
● Compact Structure: The fully welded integral ball valve features an integrated design that reduces the number of connection components, making the overall structure more compact and space-efficient. 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 inside the pipeline.
● Strong Corrosion Resistance: The main body of the ball valve is typically made from corrosion-resistant materials like stainless steel, effectively resisting the erosion of various corrosive media and extending 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 feature several notable advantages. Firstly, their robust design ensures long-term durability and reliability, capable of withstanding the harshest industrial conditions. Secondly, the use of seamless welding technology eliminates potential leakage points, enhancing safety and performance. Lastly, our commitment to quality and innovation ensures that these valves meet the latest industry standards, maximizing the value of your investment.
