The Shelly Neo Smart Water Valve NAS-WV02W is an intelligent, NSF-certified water shut-off valve made of brass with protection class IPX7 for use in drinking water systems. It uses ultrasonic-based measurement without moving parts to precisely measure flow, water pressure and temperature. The measured values are displayed and logged in real time, including total consumption and history via the Shelly Smart Control app via WLAN (2.4 GHz & 5 GHz) or Bluetooth 5.0. The fast opening and closing function enables reliable water control, supports automations and scenes as well as notifications in the event of leaks or limit value violations.

The valve can also be controlled locally via the integrated web interface or MQTT. With a standard DN25 (G1-1/4 BSPP) connection and adapter included in the scope of delivery, it is suitable for domestic and commercial applications - such as leak and flood protection, remote control of the water supply or intelligent irrigation.
