Valve and electric actuator housing

A valve, comprising:

• a valve housing;
• a valve element movably arranged in the valve housing;
• at least one electric actuator fixed to the valve housing and configured to actuate the valve element;
• an electronics unit configured to electronically control the valve;
• an electronics unit housing in which the electronics unit is arranged, the electronics unit housing having a housing pedestal configured to fasten the electronics unit housing to the valve housing, the housing pedestal having a housing aperture via which the at least one electric actuator is electrically connected to the electronics unit and which is arranged opposite the at least one electric actuator;
• and
• a seal which has a ring shape and which bears outwardly against the housing pedestal and bears inwardly against the actuator,
• wherein the housing aperture has a first step defining a first inner periphery and a second step defining a second inner periphery that is coaxial with and smaller than the first inner periphery, the first and second steps adjoined via a substantially planar abutment surface,
• wherein play in a longitudinal direction of the valve is provided between the housing aperture and at least one component, provided within the housing aperture, of the at least one electric actuator, and
• wherein, throughout the entire provided play, the seal in its entirety has a plurality of longitudinal positions relative to the housing aperture, the seal at each position configured to surround the second inner periphery while bearing against the abutment surface.
