A fully welded ball valve is a type of valve that features a fully welded structure, where the valve body, seat, and ball are joined into a single unit through welding. 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, making them essential equipment in these sectors.
● Compact Structure: The fully welded integral ball valve boasts an integrated design that minimizes the number of connecting parts, resulting in a more compact and space-efficient overall structure. This design also facilitates easier installation and maintenance.
● Excellent Sealing Performance: The welding connection method eliminates potential leakage issues associated with traditional connections, thereby enhancing the valve's sealing performance and ensuring a stable flow of the medium within the pipeline.
● Strong Corrosion Resistance: The ball valve body is typically constructed from corrosion-resistant materials such as stainless steel, effectively combating the erosion caused by 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 compelling attributes. To begin with, its robust construction guarantees long-term durability and dependability, capable of enduring the most severe industrial conditions. Additionally, the use of seamless welding technology eradicates potential leak points, enhancing both safety and performance. Lastly, our dedication to quality and innovation ensures that this valve adheres to the latest industry standards, offering the utmost value for your investment.
