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 performance, low water pressure start-, easy to install, safe to use. Can be perfectly used for water dispenser, water purifier, water vending machine, etc. High quality material, which is sturdy- and durable in use.
