A valve assembly comprises a housing and a plurality of valves disposed within the housing. The housing has a layered body which comprises a first layer and a second layer, which in combination define a fluid supply channel, a first plurality of fluid channels and a second plurality of fluid channels. Each valve of the plurality of valves may be in fluid communication with the fluid supply channel and respectively at least one fluid channel selected from the first plurality of fluid channels and the second plurality of fluid channels. The fluid supply channel partitions the layered body such that the first plurality of fluid channels is arranged on a first side relative to the fluid supply channel and that the second plurality of fluid channels is arranged on a second side opposite to the first side relative to the fluid supply channel.
