ABSTRACT OF THE DISCLOSURE A four-way ball type valve including a spherical valve element operable to as many as four positions and which 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 inter- rupting the brake control valve connection with the brake pipe, or in cutting out the brake control valve while estab- lishing brake pipe continuity through the train.
