Q41F type PN6~PN25 flanged ball valve is used to cut off or connect the medium in the pipeline, choose different materials, can be respectively suitable for water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, Oxidative media, urea and other media.
1. Among various valves, the flow resistance of the ball valve is small. When the full-diameter ball valve is opened, the diameter of the ball channel, the valve body channel and the connecting pipe are equal and form one diameter, and the medium can flow through almost without loss.
2. The ball valve can be fully closed and fully opened by rotating 90°, opening and closing quickly. Compared with the gate valve and globe valve of the same specification, the ball valve is small in size and light in weight, which is convenient for pipeline installation.
