Three way ball valve are used to switch, mix and divide the flow of corrosive or non corrosive liquid, gas or power mediums -46℃~+200℃.Upon opening and closing, the smooth flow channel effects less pressureloss, making opeartion quite labor-saving and main tenance fairly easy. The five types of flow direction(figure on the right,1 for L-shaped  and4 for t-shaped) meet different technological requirements. It can be hand,  pneumatic and electrically operated.
