Shelly FrankEver Water Valve DN25

The Shelly FrankEver Water Valve DN25 is a smart, motorized valve for precise control of the water supply in households, gardens, and industrial environments. It is drinking water certified and features an integrated Shelly chip that unlocks all Shelly functions and allows integration into numerous smart home ecosystems. Thanks to WiFi and Bluetooth connectivity, the valve works without a hub, can serve as a WiFi range extender and BLE gateway, and can be conveniently controlled via the Shelly Smart Control app or voice assistants like Alexa. The precise valve control from 0 to 100% allows the water flow to be regulated accurately, so irrigation systems, pool installations, or house connections can be optimally adjusted. An optional DS18B20 temperature sensor enables temperature-based automations to protect pipes at falling temperatures and prevent frozen pipes. In the event of a power failure, the emergency power function ensures that the valve automatically opens or closes. Power is supplied via a standard USB Type-A connector with 2 A, making installation simple and flexible. In combination with a Shelly Flood Sensor, the valve forms an effective automated water leak prevention system that detects water leaks and immediately shuts off the main water supply. This solution is suitable for homes, commercial properties, warehouses, and industrial facilities where water leaks could cause significant damage. Early detection and immediate shutdown of the water supply reduce property damage, meet insurance requirements, and ensure operation. The smart valve control optimizes water consumption and ensures safety and comfort in the smart home.

Warning: It can never be ruled out that with irrigation, the valve or the hose may become defective. We do not cover any costs caused by water damage.
