Abstract
A valve (1), in particular expansion valve, is described including a valve element (6) driven by a rotary motor (7), wherein the motor (7) includes a rotor (9) arranged inside a motor section (19) of a tube (14) and a stator (8) arranged outside the motor section (19) of the tube (14) and the rotor (9) is supported by a bearing (15), which bearing (15) is mounted with press fit in a bearing section (16) of the tube (14). Such a valve should have a small motor and a tube which can be produced with low costs. To this end the motor section (19) and the bearing section (17) include different diameters.
