The fully welded ball valve is renowned for its sophisticated structural design, which employs advanced welding techniques to ensure a tight connection between the valve body, seat, and ball. This design significantly enhances the valve's strength and sealing performance, allowing it to operate stably even in extreme conditions such as high pressure and high temperature. Thanks to its outstanding performance, the fully welded ball valve has found widespread application in industries like oil, chemical, and natural gas, becoming an essential component in these sectors.
● Compact Structure: The fully welded integral ball valve features an integrated design that decreases the quantity of connection components, resulting in a more compact and space-efficient structure. This design not only streamlines installation and maintenance but also improves sealing performance.
● Excellent Sealing Performance: Welded connections eliminate common leakage problems associated with traditional connections, ensuring a stable flow of the medium within 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 valves boast numerous significant advantages. Firstly, their robust construction ensures long-lasting durability and reliability, capable of withstanding the most challenging industrial environments. Secondly, the use of seamless welding technology effectively eliminates potential leakage risks, enhancing safety and overall performance. Lastly, our commitment to quality and innovation ensures that the valves meet the latest industry standards, maximizing your return on investment.
