Operating at 220V with a max current of 4A, it supports water temperatures up to 70℃ and activates at ultra-low pressures above 0.03KG. Its spark-free electronic components and stainless steel reset spring ensure safe, durable, and reliable flow control, ideal for low-pressure water systems and solar water heaters. ## Description Features: This water flow switch uses water flow magnetic control device and on-off control sensing elements, so as to switch on or off pump. Stable performance; induction chamber, magnetic control chamber and electronic components are designed separately in order to avoid switch failure caused by iron matter in pipeline is magnetic adsorbed. High temperature resistant materials allows the product to be used for both hot(up to 70℃) and cold water. Low water pressure startup; reset spring is made of high quality stainless steel; it can start up pump when water pressure is >0.03KG. The electronic components as control device will not cause spark during work which is quite safe. This product is widely used for low pressure area family, especially important for low water pressure ignition start-up of water heater, automatic water cycle of solar water heater.
