  • Patent number: 12291854
    Abstract: Systems and methods are provided for automatically actuating preexisting water shut-off valves upon detection of leak conditions. A coupling of a valve actuator is connected to a handle of the valve, such that a motor of the valve actuator causes the selective opening and closing of the valve. A controller obtains water flow data from a non-intrusive flow sensor (e.g., an ultrasonic sensor) clamped onto a pipe attached to the valve in close proximity thereto, as well as obtaining additional sensor data from remote sensors disposed elsewhere in the water supply system (e.g., pressure levels measured by an in-line pressure sensor). When the controller determines a leak condition exists based upon the water flow data and the additional sensor data, it controls the actuator to close the valve. The controller may also test for leaks by periodically shutting the valve and measuring the pressure while the valve is shut.

  • Patent number: 12287042
    Abstract: Various embodiments of the teachings herein include an actuator for a flap or for a valve for adjusting a gaseous or fluid volume flow. The actuator may include: a housing; an electric motor disposed in the housing; a downstream reduction gear; and a positioning element with an actuator connection for the flap or the valve. There is an electromagnet adjacent to an outer side of the rotor with a coil arrangement with a magnetic core. There is an electrical circuit arrangement for activating the electromagnet, providing a first brief current pulse, so a remanent magnetic field remains in the coil core. In a holding position of the actuator, while a mechanical pre-tensioning is set up, there is a holding torque with contact to the outer side of the rotor. The circuit arrangement provides a second brief current pulse to extinguish the remanent magnetic field still present in the coil core for releasing the holding torque with contact, forming an air gap between the electromagnet and the outer side of the rotor.

  • Patent number: 12281718
    Abstract: An adapter connects to a mechanical interface of valve on one side of the adapter and connects to an actuator mechanical interface of a valve actuator on another side of the adapter. A transmission element in the housing of the adapter transmits an actuator force developed by the valve actuator to the valve via the valve mechanical interface. The valve mechanical interface on the adapter fluidically seals to a leaking portion of the valve. Consequently, in a system in which a valve is leaking, rather than replacing or repairing the valve, the adapter may simply be interposed between the valve and the valve actuator.

  • Patent number: 12270478
    Abstract: A break away check valve that minimizes water hammer effect while closing and for use with a wet barrel fire hydrant and water main is provided. The valve includes a controllable resistance system that applies a desired resistance (dampening) to the valve's valve plates as the valve plates translate from an open position to a closed position. The resistance system includes a hydraulic piston with a tapered end that moves through an orifice filled with oil. As the increasing diameter of the piston moves into and passes through the orifice, the resistance to the piston increases. With the piston physically engaged with the valve plates, the valve plates are dampened accordingly.
