Q41F type PN6~PN25 flange ball valves are used to shut off or connect media in pipelines. Different materials can be selected to be suitable for various media such as water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, and urea.

Product Features

1. Among various valves, ball valves have low flow resistance. When a full-bore ball valve is opened, the ball passage, valve body passage, and connecting pipe diameter are equal and form a straight diameter, and the medium can flow through with almost no loss.

2. The ball valve only needs to rotate 90° to be fully closed or fully opened, and the opening and closing are quick. Compared with gate valves and globe valves of the same specifications, ball valves have a small volume and light weight, making them easy to install in pipelines.
