Runxin Wireless Auto-Shutoff Valve Leak Detector System

Runxin Wireless Auto-Shutoff Valve – Smart Leak Prevention System

The Runxin Wireless Auto-Shutoff Valve is a smart, self-contained solution designed to instantly stop water flow in the event of a leak, protecting homes, businesses, and equipment from water damage. Featuring a built-in wireless controller and durable ceramic-sealed electronic ball valve, the F104H responds to signals from up to five wireless water immersion detectors (F104F) placed throughout your space.

With a built-in rechargeable lithium battery for power outages, wireless activation, and robust brass construction, the Runxin Wireless Auto-Shutoff Valve is ideal for automated water control in high-risk areas like geysers, kitchens, and filtration systems.

When the F104F Sensor comes in contact with water, it'll send a signal to the Leak Detecting system, which will then trigger the valve, turning the ceramic ball valve inside and shutting off the water supply. Shutting off the water supply will help to prevent further leakingage, and help to prevent additional damage and/or water wastage.No water coming from the main supply, will also act as a signal that there has been a leak somewhere, where one of the water immersion sensors has been placed. 

The Runxin Smart Leak detecting system can wirelessly "link up" with a maximum of five F104F Sensors. 

Key Features:

• Main Control Valve (F104H):
