An electrically operated pre-mix valve includes a cup lever operable to activate a switch to energize a solenoid. The solenoid operates a first lever, which then contacts and operates a second lever. The second lever, in turn, moves against the contact end of an actuating shaft. The actuating shaft is thereby moved to permit beverage flow through the valve and out of a nozzle thereof. Thus, the valve herein uses a compound lever system to gain a mechanical advantage for substantially lessening the opening force required to be applied by the solenoid.
