The Shelly - Neo Smart Water Valve NAS-WV02W is a professional smart water valve designed for potable water systems, featuring ultrasonic measurement technology, remote control, and automatic leak protection. The NSF-certified brass DN25 valve is recommended for apartments, holiday homes, offices, or commercial buildings where water consumption monitoring, remote intervention, or irrigation control may be required.
The device measures water flow, pressure, temperature, and total consumption in real time. Thanks to its ultrasonic measurement system, it contains no mechanical wear components. This ensures long service life, high accuracy, and minimal maintenance requirements. Measured data can be displayed in detailed daily, weekly, or monthly charts within the Shelly Smart Control application.
Thanks to the Shelly collaboration platform, the Neo Smart Water Valve supports both Wi-Fi and Bluetooth connectivity, allowing easy integration into smart home systems without requiring a dedicated hub. Working together with the Shelly ecosystem, it can automate irrigation, optimize water usage, and provide leak protection. When paired with a Shelly Flood sensor, the system can automatically shut off the water supply if a leak is detected.
The device features a fast opening and closing mechanism, ensuring immediate response to manual control or automations. The local web interface and MQTT support enable full local integration with advanced automation systems.
The Neo Smart Water Valve is especially useful for applications such as remote water supply control, holiday property or rental supervision, precision irrigation automation, detection of unusual water consumption patterns, and prevention of water damage caused by leaks.
