  • Fluid flow control valve equipped with a conical flap and system comprising such valve
    Patent number: 11236831
    Abstract: A valve for controlling a fluid flow includes a valve body, a shutter component configured to be able to transition from an open position allowing the circulation of fluid, to a closed position preventing the circulation of fluid. The component is characterized in that it includes a fixed conical support integral with the valve body, a conjugate conical flap rotationally movable relative to the fixed support, and fluid passage apertures respectively arranged in the conical flap and in the fixed support, and an actuator of the shutter component adapted to be able to control the position of the shutter component.

  • Fluid flow control valve equipped with an electric actuator and system including such a valve
    Patent number: 11143326
    Abstract: A fluid flow control valve includes a valve body, a closing member arranged in the valve body and configured so that it can have at least one first position, called the open position, in which it allows the flow of fluid to flow freely in the valve body, and at least one second position, called the closed position, in which it prevents the fluid flow from flowing in the valve body between the fluid inlet and the fluid outlet, an electric actuator of the closing member that is suitable for being able to control the position of the closing member in the valve body, characterized in that the electric actuator is arranged in the valve body so that it can be cooled by the flow of fluid flowing in the valve body.
