<p>A valve unit includes a valve housing formed with an interior passage which communicates with an inlet opening and an outlet opening. A valve assembly is accommodated in the passage and includes a sleeve formed with a valve seat and a valve element which is biased by a biasing spring and is shiftably accommodated in the passage. The valve assembly can be so positioned in the passage that in one orientation the valve element is permanently biased into engagement with the valve seat and in another orientation in which the valve element is permanently biased out of engagement with the valve seat. A drive unit is provided which includes a drive housing that is removably connected with the valve housing, and an electromagnetic drive which, when energized serves to shift the valve element in the passage counter to the biasing force of the spring.</p>
