1 . The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2 . Simple structure, small size and light weight.
3 . Tight and reliable. At present, the sealing surface material of ball valves is widely used in plastics and has good sealing performance. It has also been widely used in vacuum systems.
4 . Easy operation, fast opening and closing, only need to rotate 90 ° from fully open to fully closed, which is convenient for long-distance control.
5 . Easy maintenance, simple structure of ball valve, seal ring is usually movable, and it is more convenient to disassemble and replace.
6 . When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
Notes When Use
1 . It should ensure that the pipe is blown clean before installation.
2 . When installing, make sure that the flow direction indicated by the arrow on the valve body should be consistent with the flow direction of the fluid.
3 . This valve has been degreased. Store and keep clean when installing.
4 . After the pipeline construction is completed, all the valves on the pipeline should be opened, and the residue in the pipeline should be thoroughly and thoroughly kept to ensure that the pipeline system is clean and free of debris.
5 . The installation system diagram with the oil-free requirements should be degreased.
6 . Slowly open and close during use.
7 . If the precision parts such as the valve disc, valve seat and valve stem are worn or damaged, it must be repaired and replaced in time.
8 . For parts such as gaskets and sealing materials, replace them with new ones each time.
1. If customers have special requirements for products, they must provide the following instructions in the order contract:
