A beverage dispenser of the type having a diluent mixed with a syrup to produce the beverage to be dispensed is provided with a solenoid actuated valve arrangement between the diluent and/or syrup supply line and the dispensing nozzle and which solenoid valve has a sealing arrangement which, upon actuation of the solenoid, provides sequential first and second stages of pressure drop across the valve seat, thus to reduce the power required to operate the solenoid and open the valve or enable the valve to operate under higher fluid pressures without increasing the power of the solenoid.
