What is a three-way ball valve?
Three-Way Ball Valve
The three-way ball valve is divided into two types: T shape and L shape. The latter can connect the two vertical pipes; The former can be applied to the distributary, interflow, and switching, the pore canal of the T shape can connect the three passes or the passes of the three. The three ways ball valve usually uses the construction of the two valve seat and it can also use the construction of the four-valve seat according to the user's demands. In this installation, any entrance can be used by an inlet that will not leak in any case. The seal construction has two constructions: soft seal and metal seal which can be applied to different industrial and mineral conditions accordingly.
