Fully welded ball valves are known for their complex structural design, which utilizes advanced welding techniques to ensure a tight fit between the valve body, seat, and ball. This design significantly improves the strength and sealing performance of the valve, enabling it to operate stably and reliably even under extreme conditions such as high pressure and high temperature. Due to its excellent performance, fully welded ball valves are 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, minimizing the number of connecting components to achieve a more compact and space saving structure. This design not only simplifies installation and maintenance, but also improves sealing performance.
● Excellent Sealing Performance: Welding connections eliminate common leakage problems associated with traditional methods, ensuring stable flow of media inside the pipeline.
● Strong Corrosion Resistance: Ball valve bodies are usually made of corrosion-resistant materials such as stainless steel, effectively resisting erosion caused by various corrosive media and extending their 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 offer several significant advantages. Firstly, their robust design ensures long-lasting durability and reliability, capable of withstanding a variety of extreme industrial environments. Secondly, by employing advanced seamless welding technology, we have effectively eliminated potential leakage risks, significantly enhancing the product's safety and overall performance. Lastly, our commitment to quality and innovation ensures that the valves fully comply with the latest industry standards, maximizing your return on investment.
