The invention relates to a fluid leakage protection device, comprising a central shutoff valve, an actuator which is mechanically coupled to the shutoff valve in order to open and close the shutoff valve, a control unit which is connected with respect to signaling technology to the actuator and is designed to control the actuator, a sensor which is connected with the respect to signaling technology to the control unit and which is designed to detect a fluid request of a peripheral device and to transmit a fluid request signal to the control unit, said control unit being designed to control the actuator for moving the shutoff device into the open position when receiving the fluid request signal. According to the invention, the sensor comprises a rotor with wing parts and a magnetic north and south pole, which is rotationally mounted inside the sensor housing, and to a magnetic field sensor which is secured to the sensor armature for detecting a through-flow of a medium through the armature by detecting the rotation of the rotor.

The invention relates to a building water safety device, comprising a shut-off valve that has an inlet opening, an outlet opening, a valve channel, which connects the inlet opening to the outlet opening, and a shut-off element, which releases the valve channel for the passage of a medium from the inlet opening to the outlet opening in an open position and blocks the valve channel in a closing position, and comprising an actuator, in particular an electromechanically actuated actuator, that is mechanically coupled to the shut-off element and designed to move the shut-off element from the open position to the closed position and vice versa. According to the invention, a sensor device for detecting the presence of a person in the area of a water removal point and a control device are provided, which control device is coupled to the sensor device and the actuator with regard to signals and is designed to control the actuator to move the shut-off element to the open position if a sensor signal signaling the presence of a person in the area of the water removal point is received from the sensor device and/or to control the actuator to move the shut-off element to the closing position if a sensor signal signaling the absence of a person in the area of the water removal point is received from the sensor device.

The invention relates to an external wall valve, comprising an inlet opening (3), an outlet opening (4), a liquid conducting path (5a-5f), which extends from the inlet opening to the outlet opening, a ventilation opening (91) for feeding air into the housing pipe (80), a blocking valve (20) arranged in the liquid conducting path that, in an open position, releases a liquid connection between the inlet opening and the outlet opening along the liquid conducting path through the housing pipe and, in a closed position, blocks said liquid connection, an operating handle (71) arranged at the second end of the housing pipe for moving the blocking valve from the open position to the closed position and vice versa, and a ventilation valve unit (40, 41) that, in an open position, releases an air connection between the ventilation opening and the liquid conducting path within the housing pipe and, in a closed position, blocks an air connection between the ventilation opening and the liquid conducting path within the housing pipe. According to the invention, an air conducting path (8a, 8b) extending in parallel and separately next to the liquid conducting path is present in the housing pipe in order to feed air into the housing pipe.
