Features: When water flows through the preset flow channel, it displaces the magnet. As the magnet moves near the 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: 300ml/min, response time: less than 1 second. Lightweight, compact design, stable performance, low water pressure activation, easy installation, safe operation. Suitable for use in water dispensers, water purifiers, water vending machines, and similar applications. Constructed from high-quality materials for durability and long-term use.
