APPARATUS FOR CLEANING LIQUID CONVEYING SYSTEM AND CONTROL VALVE ASSEMBLY THEREFOR Abstract of the Disclosure Cleaning apparatus for a vacuum-operated milk conveying system in a dairy comprises a cleaning liquid tank, timer- controlled components which periodically supply fresh clean- ing liquid to the tank, connections by which liquid in the tank (fresh or used) is periodically provided to the system, and a timer-controlled drain control valve assembly mounted on the tank. The valve assembly comprises two (upper and lower) sym- metrical molded plastic valve housings secured on opposite sides of a horizontal plate having sets of holes therein which are cooperable with chambers, ports and openings in the housings. The valve assembly also comprises an inlet port, an outlet port, a circulating port, and a single solenoid for operating three rod-mounted valves, namely: a fill valve located between the inlet port and the circulating port, a dump valve located between the inlet port and the outlet port, and a drain valve for a drain port on the tank. When the solenoid is de-energized, the drain valve closes to allow the tank to fill and used cleaning liquid from the system is directed from the inlet port, through the fill valve and through the circulating port into the tank for recirculation. When the solenoid is de-energized, the drain valve opens to allow the tank to empty and used cleaning liquid from the system is directed from the inlet port, through the dump valve and through the outlet port for dis- posal elsewhere than into the tank.
