Abstract:
A liquid dispensing valve (12) including a liquid inlet (90) for receiving the liquid and a liquid outlet (92) for discharging the liquid. A valve member (44) is mounted for movement relative to the liquid outlet (92) between open and closed positions. A liquid passage (96) communicates between the liquid inlet (90) and the liquid outlet (92). An air inlet (114) is provided for receiving air from a source of pressurized air. An air passageway (120 and/or 128) is coupled with the air inlet (114). A pneumatic actuator (40, 110, 112) communicates with the air passageway (120 and/or 128) for moving the valve member (44) at least to the open position. An electrically operated air supply device (70) interacts with the air passageway (120 and/or 128) so as to control the flow of pressurized air to the pneumatic actuator (40, 110, 112).
