A beverage dispenser includes a body having a bore with an inlet, an outlet and a valve seat therebetween. A valve stem has a seal to selectively engage the valve seat to open and close the bore to a flow of beverage between the inlet and outlet. A serving lever is pivotally connected to the body and selectively coupled and decoupled to the valve stem by a clutch which is operated by a solenoid. Operating the serving lever may move the seal away from the valve seat only when clutch couples the serving lever to the valve stem. A control circuit operates the solenoid to cause the clutch to decouple the serving lever from the valve stem when the beverage has been dispensed continuously for greater than a defined period of time.

Solenoid control circuitry can be used with either a first solenoid requiring a relatively large holding current or a second solenoid requiring a relatively small holding current. A solenoid connected with the solenoid control circuitry is initially energized to effect operation of the solenoid from an unactuated condition to an actuated condition. A detector detects whether a characteristic of the initial energization of the solenoid corresponds to a characteristic of the first solenoid or the second solenoid. The solenoid control circuitry varies the amount of holding current supplied to the solenoid as a function of whether the detector detects the first solenoid requiring the relatively large holding current or the second solenoid requiring a relatively small holding current. A fault detection circuit is provided to interrupt energization of the solenoid in the event of an excessive flow of current.
