application:
there are t-type and l-type 3-way ball valve.t-type can make sure 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-way ball valve 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.
