A plurality of manifold valve assemblies each including a generally vertical valve cylinder having an inlet port at its top and at least two outlet ports near its bottom. A single actuator valve is fitted for closing each of the ports, each including a valve actuator, an actuator rod attached to and actuatable by the actuator, one end of the rod projecting outward from the actuator, and at least one valve plug attached to the projecting end of the actuator rod. Two of the three valves have rods that are coaxial with each other, the rods being independently actuatable by their respective actuators, both closing in the same direction so that no valve cage or bonnet is required.
