3 way and 4 way ball valves can contain additional detail that defines the type of ball drilling which is either a t or l port ball. Pipe material expand collapse. The one piece valve body improves structural integrity of the pressure boundary by eliminating leak paths that could be caused by the gaskets in two piece bolted valve designs. For those designs without a spring reverse flow is required to move the ball toward the seat and create a seal.
