 Flange ball valve

Reduced flange all welded ball valve

All welded ball valves are widely used in various fields. Its service life is far better than that of steel ball valve, steel pipe, steel pipe, steel pipe, steel pipe, etc. All welded ball valve can operate reliably for a long time without maintenance. It is easy to install, which makes the installation of valve more convenient.

Flange ball valve advantage

Ball valve is a new type of valve widely used, which has the following advantages:

1. The flow resistance is small, and its resistance coefficient is equal to that of the same length of pipe.

2. It has the advantages of simple structure, small volume and light weight.

3. It is compact and reliable. The sealing surface material of ball valve is widely used in plastic, with good sealing performance. It is also widely used in vacuum system.

4. It is easy to operate and quick to open and close. Only 90 ° rotation is needed from full opening to full closing, which is convenient for remote control.

5. Maintenance is convenient, ball valve structure is simple, seal ring is generally movable, disassembly and replacement are more convenient.

6. When the valve is fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, which will not cause erosion of the valve sealing surface when the medium passes through.

7. Wide range of application, diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied. This kind of valve should be installed horizontally in the pipeline.
