Hard-sealed ball valve

[Use of the product]

Q41Y/Q347Y type PN16~PN64 fixed 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, and different materials are selected. It can be applied to water, steam, oil, liquefied gas, natural gas, gas, nitric acid, acetic acid, oxidizing medium, urea and other media respectively.

[Product Features]

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

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