ABSTRACT:
A liquid flow-restriction device has a plurality of flow-restriction passages connected to a common outlet. Each flow-restriction passage has a magnetically operable valve having a valve member movable between an open position and a closed position. The valves are operated by a common actuating element selectively positionable with respect to the valve members to open the valves. The actuating element is a permanent magnet. The device is simple and allows easy selection of a flow rate to a dilution dispenser.
