National standard flange ball valve

[Product Use]

Q41F type PN16~PN64 flange ball valve is used in various pipelines of Class150~Class1500, PN16~PN64,

JIS10K~JIS20K. It is used to cut off or connect the medium in the pipeline. Different materials are selected, which can be applied to water, steam, oil, liquefied gas, natural gas, nitric acid, acetic acid, oxidizing medium, urea and other media.

[Product Features]

1. In various valves, the flow resistance of the ball valve is small. When the full-diameter ball valve is opened, the ball channel, the valve body channel and the connection pipe diameter are equal in diameter, and the medium can flow through almost without loss.

2. The ball valve can be fully closed by rotating 90°, and it can open and close quickly. Compared with gate valves and globe valves of the same specifications, the ball valve is small in size and light in weight, which is convenient for pipeline installation.
