Four way ball valve is a spherical type of valve. It is operable to as many as four positions. It can be installed on a railway car in place of the branch pipe tee to eliminate the need for an angle cock at each end of the brake pipe and a brake control valve cut-out cock. The ball valve is functionally analogous to a rotary valve in cutting off the brake pipe at either end of the car without interrupting the brake control valve connection with the brake pipe, or in cutting out the brake control valve while establishing brake pipe continuity through the train.
