This ensures that you can easily manage your valves without manual effort, making it ideal for preventing leaks. Leak and Gas Alarm System: Can be used with any water or gas sensor alarm (not included), this valve offers added protection for your home or business. When a water or gas leak is detected, the device receives a signal to close the valve, helping prevent potential accidents and improve safety.

Whether you're at work or on vacation, a simple tap on your smartphone is all it takes to open or close the valve.

Use voice commands to open or close the valve, enabling hands-free control and seamless integration into your smart home ecosystem. Scheduled and Scene-Based Control: Use the app to set up scheduled, delayed, or recurring timing controls. For example, schedule the valve to close at 7:30 AM when leaving for work and automatically open at 5:30 PM when returning home. Create smart scenes that trigger the valve based on location, such as closing when leaving a designated area and opening upon arrival, enhancing convenience and safety. Reliable Construction: Easy to install and use with stable performance. The valve housing is made of environmentally friendly, flame-retardant plastic material, reducing safety risks.
