A valve for dispensing a liquid includes a housing, an internal liquid passage extending through the housing, a valve seat, a valve member movable between a closed position engaging the valve seat and an open position disengaging the valve seat, and a control member controlling movement of the valve member, which is movable between a first position in which it engages the valve member in its closed position, a second position in which the valve member is in its open position but still engaging the control member and a third position in which the valve member is in its open position and out of engagement with the control member. At least one air passage connects the outside of the valve with the internal liquid passage. The at least one air passage is closed in the first and second positions of the control member and is opened in the third position.

1. A valve for dispensing a liquid, comprising a housing, an internal liquid passage extending through the housing between an inlet and an outlet, a valve seat, a valve member configured to move between a closed position engaging the valve seat for closing the internal liquid passage and an open position disengaging the valve seat for opening the internal liquid passage, and a control member configured to control movement of the valve member between the closed and open positions, wherein the control member is configured to move between a first position in which the control member engages the valve member for keeping the valve member in the closed position, a second position in which the valve member is in the open position but still in engagement with the control member and a third position in which the valve member is in the open position and out of engagement with the control member, wherein at least one air passage is defined between the valve member and the control member to connect an outside of the valve with the internal liquid passage and wherein said at least one air passage is closed in the first and second positions of the control member and is opened in the third position of the control member. 2. The valve according to claim 1, wherein the valve member and the housing have cooperating abutments to define the open position of the valve member. 3. The valve according to claim 2, wherein the housing comprises a circumferential step and the valve member comprises a circumferential protrusion for cooperation with said circumferential step. 4. The valve according claim 1, wherein the control member is biased to the first position. 5. The valve according to claim 4, wherein the control member is biased by a spring positioned between the housing and the control member. 6. The valve according to claim 5, wherein the spring is a compression spring. 7. The valve according to claim 4, wherein the valve member is biased to the open position, wherein a bias on the valve member is less than a bias on the control member. 8. The valve according to claim 7, wherein the valve member is biased by a spring positioned between the housing and the valve member. 9. The valve according to claim 8, wherein the spring is a compression spring. 10. The valve according to claim 1 wherein the control member is provided with at least one operating tab protruding outwardly through an opening in the housing. 11. The valve according to claim 10, provided with two operating tabs positioned diametrically opposite to each other. 12. The valve according to claim 1, wherein the valve member is provided with a liquid collector that is liquid tight and movable to engage the valve seat, the liquid collector having a first inner liquid channel that in the open position of the valve member communicates with a valve passage through the valve seat. 13. The valve according to claim 12, wherein the liquid collector has circumferential inner and outer surfaces, whereas the control member defines a second inner liquid channel communicating with the first inner liquid channel of the liquid collector and has a circumferential inner surface, whereas the at least one air passage is defined as an annular channel that extends between the circumferential outer surface of the liquid collector and the circumferential inner surface of the control member and that debouches into the second inner liquid channel, wherein in the first and second positions of the control member the circumferential inner surface of the control member in a sealing manner engages the circumferential outer surface of the liquid collector for closing said annular channel, whereas in the third position of the control member the circumferential inner surface of the control member disengages the circumferential outer surface of the liquid collector for opening said annular channel. 14. The valve according to claim 13, wherein the annular channel in a region where the annular channel debouches into the second inner liquid channel is provided with turbulators. 15. The valve according to claim 14, wherein the second inner liquid channel of the control member has a narrowed throat in the region where the annular channel debouches into the second inner liquid channel and wherein the turbulators are positioned immediately before said narrowed throat. 16. The valve according to claim 14, wherein the turbulators comprise a circumferential step in the circumferential inner surface of the control member. 17. The valve according to claim 13, wherein in at least one of the circumferential inner surface of the control member and the circumferential outer surface of the liquid collector longitudinal grooves are provided. 18. The valve according to claim 13 wherein the circumferential inner surface of the control member and the circumferential outer surface of the liquid collector taper for defining a tapering annular channel there between. 19. The valve according to claim 1, wherein the outlet is provided with a restrictor. 20. The valve according to claim 1, wherein a connector is provided at an inlet for the valve configured to allow a liquid tight connection between the valve and a spigot or spout of a liquid reservoir. 21. The valve according to claim 12, wherein the liquid collector engages the valve seat through a deformable seal member attached both to the liquid collector and to the valve seat. 22. A liquid dispensing device for use with a flexible bag containing said liquid and having a spigot or spout connected thereto, the liquid dispensing device comprising a device housing configured to receive the flexible bag, wherein the device housing is provided with a receiver configured to receive the spigot or spout, wherein the receiver comprises a valve according to claim 1 wherein an inlet of the valve is provided with a connector configured to provide a liquid tight connection between the valve and the spigot or spout of the flexible bag. 23. The liquid dispensing device according to claim 22, wherein the valve is provided in an upper part of the housing and wherein the housing further is provided with a support member for the flexible bag, wherein the support member is movable between a lowermost position remote from the valve for supporting a full bag and an uppermost position near to the valve for supporting a substantially empty bag. 24. The liquid dispensing device according to claim 23, wherein the support member has an inclined upper support surface sloping down to a side of the valve.
