ABSTRACT:
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, a hollow cylindrical valve stem attached to the projecting end of the hollow actuator rod, having a valve plug for opening and closing an inlet port, the valve plug having a central opening through which the first actuator is fitted, the other two valves having valve plugs for opening and closing outlet ports, and being independently controllable by a valve actuator, one of the outlet ports. The outlet ports are configured so that liquids will drain by gravity from the lower end of the cylinder into either one of the outlet ports when the other of the outlet ports is closed.
