TL;DR: In this article, the flow of beer pumped from a keg by a pump (5) to barhead units (1, 2, 3) incorporating a solenoid operated bar valve (12, 16, 20) and switches (13, 17 and 21) is controlled by a flow control unit (4).
Abstract: The flow of beer pumped from a keg (7) by a pump (5) to barhead units (1, 2, 3) incorporating a solenoid operated bar valve (12, 16, 20) and switches (13, 17 and 21) is controlled by a flow control unit (4). This unit incorporates low voltage relays (24, 25 and 26) for each bar head unit and a mains relay (27), which operates pump 5. For bar head unit (1), for example, closure of switch (13) operates the valve (12) and the pump (5) to supply beer to the unit (1). Opening the switch (13) closes the valve and switches off the pump. In this way pump and valve operation can be linked together and those parts of the apparatus likely to be contacted by an operator in normal operation can be fed from a low voltage supply, produced from mains voltage by step-down transformer (28).
