- Intelligent toilet valve that can be used with a pressure reducing valve, a voltage regulator valve, or a solenoid valve; supports DC 12V, 24V and AC 220V power supplies. - Flow switch with 12V or 24V is a key component that connects with the intelligent toilet valve system. - The intelligent toilet valve provides multiple functions and can be combined with various valves to meet different usage needs. - The DC 12V, 24V and AC 220V voltage options make it adaptable to different electrical environments. - The valve and the flow switch work together to ensure proper system operation. - Use case 1: residential or small office install requiring DC control, paired with a pressure reducing valve and a solenoid valve for reliable operation. - Use case 2: bathroom retrofit in buildings with AC mains, using 220V supply to power the valve and flow switch. - Use case 3: projects that require flexible valve configurations, allowing mixing with different valve types to tailor functionality.
