Abstract: Exemplary embodiments are directed to devices, methods and systems capable of pressurization, generally involving a flow system that includes a pressurized reservoir, at least one pump including a pump control valve, an outlet port, a shut-off valve and a vent valve. The flow system is configured to be pressurized. The shut-off valve is disposed between the pressurized reservoir and the at least one pump. The vent valve is disposed between the at least one pump and the outlet port. The shut-off valve, the vent valve and the pump control valve of the at least one pump are configured to actuate in a coordinated manner to control a pressurization of the flow system. Exemplary embodiments are further directed to devices, methods and systems for column switching, generally including at least a first column, a second column and a column switching valve.
