Features:When the water flows in the preset flow channel, it pushes the magnet to displace. When it moves to the corresponding reed- tube, the reed- tube conducts after sensing the magnetic field. When there is no water flow, the magnet returns to its position under the thrust of the spring, and the reed- tube is disconnected after the corresponding reed- tube cannot sense the magnetic field.Thread: G1/4-inch, startup- flow: 300ml/min, response time: less than 1s.Lightweight, reasonable size, stable percompatiblemance, low water pressure start-, easy to install, safe to use.Can be perfectly used compatible water dispenser, water purifier, water vending machine, etc.Made of high quality material, which is sturdy and durable in use.
