Disclosed is a valve drive unit that has first and second SMA wires that can be alternatively activated. The valve drive unit further includes a pivoting member pivotably arranged around a pivoting member axis, the pivoting member including a valve driver arranged at a distance from the pivoting member axis. The first and second SMA wires are coupled to the pivoting member such that an activation of the first SMA wire causes the pivoting member to pivot into a first direction and an activation of the second SMA wire causes the pivoting member to pivot into a second direction, the second direction being opposite to the first direction. The valve driver is configured to releasably engage a valve driver coupler of a valve unit, such that, in the engaged state, a pivoting of the pivoting member is transmitted to the valve driver coupler via the valve driver.
