National standard three-way ball valve installation characteristics is intioduce
First, because the materials such as ptfe has good self-lubrication, with the sphere of the friction loss is small, so the national standard of the service life is long, the 3-way ball valve enjoys national standard three-way ball valve body channel level off is smooth, can transport viscous fluid, slurry and solid particles. 
Second, national standard three-way ball valve fluid resistance small, ball valve is the smallest of all valve fluid resistance in the class a, even reducing ball valve, the fluid resistance is small.
Third, national standard three-way ball valve seat sealing performance is good.Most ball valve sealing ring are made of elastic material such as poly vinyl four soft sealing structure is easy to guarantee the unsealed, and ball valve sealing force with medium pressure increases with the increase in.
Fourth, the national standard three-way ball valve stem seal and reliable.When the ball valve open/close the valve stem make rotation movement only and not for lifting movement, the valve stem packing seal is not easy to damage, and pour sealing stem sealing force with medium pressure increases with the increase in.
Fifth, national standard three-way ball valve switch, convenient quickly, as long as the valve rod rotation 90 o, to complete the ball valve fully open or close the action, it is easy to achieve rapid opening and closing, easy installation, can be installed on any position of the pipeline in any direction, configurable pneumatic, electric, hydraulic and so on many kinds of driving mechanism, realize the remote control and automation.
