1. A fluid circulation control valve, comprising: a valve body having a movable control member, an electrical actuator comprising a stator and a rotor, a sealing cover extending from the valve body to the inside of the stator, the sealing cover being positioned at an interface between the rotor and the stator in such a way that the rotor is inside the sealing cover and submerged in the fluid, the stator being isolated from the fluid, the rotor configured to rotate about a first axis and being secured to a shaft extending along the first axis, the movable control member configured to move in a linear manner along a second axis or to rotate about the second axis, the shaft having an end that forms, together with a toothed wheel that drives the movable control member, a gear pair with non-intersecting or intersecting axes, wherein a base of the sealing cover is inserted into the valve body and comprises a groove, a seal member disposed within the groove and providing a fluid-tight seal between the valve body and the base of the sealing cover, and wherein the sealing cover is directly fixed to the valve body.
