The release graduating proportioning valve has a proportioning piston movable between a first position at which a control volume is isolated from atmosphere to a second position at which the control volume is connected to atmosphere, to enable graduated release of brake cylinder pressure. A port to atmosphere is provided in the valve body, and the port is connected to, or isolated from, the control volume responsive to movement of the proportioning piston.
