About this product
The FrankEver Smart Water Valve DN20 is a motorized ball valve with a 3/4 inch thread that turns ordinary plumbing into a controllable water shut-off point. The body is built from SS304 stainless steel and engineering plastics, carries an IP65 rating and NSF potable-water certification, so it suits an apartment, a private house or an irrigation line.<br><br>The actuator opens and closes the valve remotely, while smooth 0–100% flow control lets you meter water precisely. The device runs on the ShellyX chip, connects directly to a 2.4 GHz Wi-Fi network and over Bluetooth 4.2 without a separate gateway, and operates locally even without internet.<br><br>Support for the DS18B20 temperature sensor enables automation scenarios such as shutting off water on a sub-zero risk or following an irrigation schedule. A built-in capacitor stores energy and completes an open or close action if power is lost.

Where it works
Use cases
An apartment in Chisinau: the leak sensor detects water on the floor and closes the DN20 valve within seconds.
The valve automatically shuts off water when a leak sensor near the washing machine or dishwasher triggers.
The owner leaves town and shuts off water with one button, removing the risk of a flood in the empty apartment.
Full remote cut-off of the riser from the app before a holiday or a long absence.
A country house in winter: on a pipe-sub-zero risk, the system automatically cuts the water supply.
With a connected DS18B20 sensor, the valve shuts off water when the temperature drops below a set threshold.

Frequently asked questions
What pipe size fits the FrankEver DN20 valve?
The valve has a DN20 thread, that is 3/4 inch, and mounts on pipes of this size. Check the diameter of your existing pipework before ordering.Does the valve need a separate hub or gateway?
No. The valve connects directly to a 2.4 GHz Wi-Fi network and over Bluetooth 4.2, and it is controlled from the Shelly Smart Control app without a separate hub.How is the valve powered and what happens during a power outage?
It is powered from a USB Type-A adapter rated 5 V / 2 A (not included). A built-in capacitor stores energy and completes an open or close action if power is lost.Can the valve shut off water automatically on a leak?
Yes. Through an automation scenario, the valve can shut off water when a compatible leak sensor detects water, for example near the washing machine.Which smart-home platforms is the valve compatible with?
The valve runs on the ShellyX chip and integrates with Home Assistant, SmartThings, Homey and the Shelly app via the open MQTT, HTTP and WebSocket (TLS) protocols.Is the valve suitable for potable water and household pressure?
Yes. The body is SS304 stainless steel with NSF potable-water certification, carries an IP65 rating and withstands a maximum working pressure of 1 MPa.
