Features: When water flows through the preset flow channel, it displaces the magnet. As the magnet moves near the corresponding reed tube, the reed tube conducts upon sensing the magnetic field. When there is no water flow, the magnet returns to its original position via spring force, and the reed tube disconnects when it no longer senses the magnetic field. Thread: G1/4 inch, startup flow: 300 ml/min, response time: less than 1 second. Lightweight, compact design, stable performance, low water pressure activation, easy installation, safe operation. Ideal for use in water dispensers, water purifiers, and water vending machines. Constructed with high-quality materials for durability and long-term use.
