There are T-type and L-type three-way ball valve.T-type can make the three positive intersection pipeline contact to each other or cutting
the third passage.Plays a role of shunting and the confluence.L-type 3-wan ball vale can contact two positive intersection pipeline,but
can't keep the third pipeline contact to each other,only play a role of distribution.3-way ball valve in pipeline mainly be used to cutting,
distribution and change the media's flow direction.
Working Principle:
3-way ball valve's working principle is by revolving valve core to turn on or off the valve
Matters need attention by installation or maintenance 3-way ball valve:
1.Need reserve place of rotary valve handle
2.Cannot be used as a throttle
3.Ball valve with transmission shall be install in vertical
