Product Description
Product Description
Natural gas high-pressure ball valves are often used to cut off or connect media in oil, natural gas, coal and ore mining, refining and processing, and pipeline transportation systems. Special ball valve and ash unloading valve for pulverized coal injection are especially suitable for blast furnace pulverized coal injection, dust and solid powder pipeline systems, air pipelines and spray gun pipelines. The natural gas high-pressure ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as frictionless switch, non-wearing seal, and small opening and closing torque. This can reduce the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium. It is widely used in petroleum, chemical, urban water supply and drainage and other working conditions that require strict cut-off. The manual ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The ball valve is a new type of valve that has been widely used in recent years. It has the following advantages:1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.2. Simple structure, small size and light weight.3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in vacuum systems.4. Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.5. Convenient maintenance, simple structure of the ball valve, the sealing ring is generally movable, it is convenient to disassemble and replace.6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should show a spherical surface at the entrance and exit, so as to cut off the flow.Certifications
