The invention relates to a connector head (12) comprising an interior space (40), a tank connector (13) which is in fluid communication with the interior space (40) and which can be fluidly connected to a valve apparatus (10) mounted on the tank (9) for filling or emptying the tank (9), a product port (14) in fluid communication with the interior space (40) and a discharge port (33) in fluid communication with the interior space (40). To allow a tank to be filled and emptied under improved hygienic conditions, it is proposed that the connector head (12) comprises a first valve (29), with which first valve (29) the product port (14) can be shut off from the interior space (40), a second valve (34), with which second valve (34) the discharge port (33) can be shut off from the interior space (40), and a cleaning device (38) adapted and arranged to clean the interior space (40) and the tank connector (13). The invention also relates to a valve block.

Kegs of beer may be connected in parallel alongside one or more valves that connect to a flushing fluid supply. When a beer is selected, the associated beer valve opens so that beer can be dispensed. After a pour is completed, the system automatically flushes the beverage tubing line clean by opening a flushing fluid valve, allowing flushing fluid to cleanse the line. This flushing of the line enables the system to dispense a beer from a recently flushed line for each pour, and/or dispense many different beers because leftovers of a beer from an earlier pour do not contaminate the line for later pours. The system is also configured to measure the time poured based on information from a sensor in a dispenser (e.g., a tap handle). The time poured and a measured flow rate are used to calculate the total price to charge a customer for the beer.

A coupler for a beverage keg has a coupler body, a first inlet for connection to the beverage keg, a second inlet for receiving compressed gas, a gas outlet adjacent the first inlet, a cleaning fluid port for connection with a flow of cleaning fluid, and a beverage port for fluid connection with a beverage dispenser. A valve has first and second valve members. The first valve member is axially movable within the coupler body between a first position in which a fluid flowpath between the second inlet and the gas outlet is closed and a second position in which a fluid flowpath between the second inlet and the gas outlet is open. The second valve member is axially movable within the first valve member between a cleaning position in which a fluid flowpath between the cleaning fluid port and the beverage port is open and a flowpath between the first inlet and the beverage port is closed, and a dispensing position in which the fluid flowpath between the cleaning fluid port and the beverage port is closed and the flowpath between the first inlet and the beverage port is open.
