The fully welded ball valve is renowned for its clever structural design, which integrates the valve body, valve seat, and ball into one unit through advanced welding technology. This design significantly improves the strength and sealing performance of the valve, ensuring stable operation under extreme conditions such as high pressure and high temperature. Due to its excellent performance, fully welded ball valves have been 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, reducing the number of connecting components, making the structure more compact and space saving. This design not only simplifies installation and maintenance, but also improves sealing performance.
● Excellent Sealing Performance: Welding connections eliminate common leakage problems in traditional connections, ensuring stable flow of media inside the pipeline.
● Strong Corrosion Resistance: The ball valve's main 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 has several significant advantages. Firstly, its sturdy structure ensures long-term durability and reliability, capable of withstanding the harshest industrial environments. Secondly, the use of seamless welding technology effectively eliminates potential leakage points, improving safety and overall performance. Finally, our commitment to quality and innovation ensures that our valves comply with the latest industry standards, maximizing your investment value.
