Abstract

An electrically actuated valve may include a housing and a cylindrical valve body mounted rotatably therein. The housing may have at least one casing-side inlet and at least one casing-side outlet. The valve body may have at least one casing-side opening, via which the inlet may be at least one of connectable to the outlet and able to be shut off from the outlet dependent on a rotary angle. A recess extending at least partially around at least one of the inlet and the outlet may be provided on an inner casing face of the housing. At least one sealing element may be provided with a base made from a first material, and a saddle-shaped sealing sliding body made from a second material joined to the first. The sealing element may engage with the base into the recess, and may slide with the sealing sliding body on the valve body.
