The fully welded ball valve is known for its clever structural design, which uses advanced welding technology to ensure a tight fit between the valve body, valve seat, and ball. This design significantly improves the strength and sealing performance of the valve, enabling it to operate stably 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 boasts an integrated design that reduces the number of connection components, making the structure more compact and space-efficient. This design not only simplifies installation and maintenance but also enhances sealing performance.
● Excellent Sealing Performance: Welded connections eliminate common leakage issues found in traditional methods, ensuring a stable flow of the medium within the pipeline.
● Strong Corrosion Resistance: The main body of the ball valve is typically made from corrosion-resistant materials such as 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 boast several significant advantages. Firstly, their robust design ensures long-lasting durability and reliability, making them 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 our valves fully comply with the latest industry standards, maximizing your return on investment.
