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 or 4-inch, startup- flow: 300ml or 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. Made of high quality material, which is sturdy and durable in use.
