  • Patent number: 11840828
    Abstract: Fluid supply assemblies for fluid systems are provided, including faucet assemblies (e.g., electrically or mechanically actuated faucet assemblies) having an integrated anti-scald device and having an integrated temperature mixing valve. An exemplary faucet assembly includes an integrated temperature mixing valve, and/or an integrated anti-scald device configured to stop the inlet flow of hot water in the event the mixed outlet water temperature exceeds a user-selected set point. The faucet assemblies can prevent scalding as defined by ASSE 1070.
