1.The
ball valve has the lowest flow resistance .
2. Because it will not get stuck during work (when there is no lubricant), it can be reliably used in corrosive media and low boiling point liquids.
3. Complete sealing can be achieved in a wide range of pressure and temperature.
4. It can realize rapid opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so as to ensure that it can be used in the automation system of the test bench. When the valve is opened and closed quickly, there is no shock in operation.
5. The spherical closure can be automatically positioned at the boundary position.
6. The working medium is reliably sealed on both sides.
7. 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.
8. With compact structure and light weight, it can be considered as the most reasonable valve structure for low temperature medium system.
9. The valve body is symmetrical, especially the welded valve body structure, which can well withstand the stress from the pipeline.
10. The closing piece can withstand the high pressure difference when closing.
11. The ball valve with fully welded valve body can be directly buried in the ground, so that the valve internals are not corroded, and the maximum service life can reach 30 years. It is the most ideal valve for oil and natural gas pipelines.
