Ball valve features:
1. The ball valve has low fluid resistance and low flow resistance (actually zero)
2. The opening and closing of the ball valve is fast and convenient.
3. The ball valve has good sealing performance.
4. The ball valve has a long service life.
5. The high reliability of the ball valve is mainly due to:
①A pair of sealing pair of ball and valve seat will not cause abrasion, sharp wear and other failures, and will not get stuck during operation (when there is no lubricant), so it can be reliably applied to corrosive media and low boiling point liquids. ；
②The built-in valve stem structure eliminates the potential accident risk that the valve stem may fly out due to the loosening of the packing gland under the action of fluid pressure;
③The ball valve with anti-static and fire-resistant structure is suitable for pipelines that transport oil, natural gas and gas.
6. Smooth and smooth passage in the valve body is more suitable for conveying viscous fluid. Slurry, and solid particles.
7. Because it will not get stuck during work (when there is no lubricant), it can be reliably applied to corrosive media and low boiling point liquids.
8. The ball-shaped closing piece can be automatically positioned in position, and can withstand the high pressure difference when closing.
9. It can achieve complete two-way sealing in a large pressure and temperature range.
10. When fully open and fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface.
11. With compact structure and light weight, it can be considered as a reasonable valve structure for cryogenic media systems.
