Q347Y American standard turbine hard seal flange cast steel ball valve

[Product Features]

1. The flow resistance is relatively small, and when the full diameter ball valve is opened, the opening of the ball valve is in an O-shape, also known as an O-shaped ball valve. The spherical channel, valve body channel, and connecting pipe diameter are equal and form one diameter, and the medium has no fluid resistance;

2. The ball valve can be fully closed and fully opened by rotating 90 degrees, with quick opening and closing. Compared with gate valves and globe valves of the same specifications, ball valves have a smaller volume and lighter weight, making them easier to install in pipelines;

3. Soft sealed ball valves with PTFE seats can be used for pipelines below 180 ° C; The valve seat using PPL is suitable for temperatures below 300 ° C; Using PEEK is more wear-resistant;

4. This manual ball valve adopts a flat head valve stem, and the connection with the handle will not be misaligned, ensuring that the switch status indicated by the handle is consistent with the valve;

5. Locking device: To prevent misoperation of valve opening and closing, there are locking holes in the fully open and fully closed positions of the valve to ensure that it is in the correct position;

6. Valve stem anti flying structure: The valve stem is bottom mounted to prevent it from flying out under pressure, and can also form metal contact with the valve body after a fire, ensuring the valve stem is sealed;

7. The cast steel ball valve with cast steel body and sphere is suitable for various media such as water, oil, and gas

8. Installing different types of execution structures can assemble automatic control valve systems into electric flange ball valves and pneumatic flange ball valves for use in automated industrial pipelines;

7. Ball valves use a spherical body with a circular through-hole as the opening and closing component. Under the drive of the valve stem, the spherical body rotates around the center of the valve stem by 0-90 degrees to complete the opening and closing function; Featuring a compact structure and quick switching, the valve can be closed and the pipeline medium can be cut off by rotating it 90 degrees; The valve stem is bottom mounted, which prevents accidents caused by valve stem penetration and ensures safe use;
