Features ????Stable and safe: Water Flow Switch does not produce sparks when working and is very safe because its induction chamber, magnetic control chamber and electronic components are designed separately, which can prevent iron in the pipe from being magnetically adsorbed and causing switch failure. ????Heat-resistant and sturdy: Water Flow Switch’s high-temperature-resistant material allows the product to be safely used in hot water (up to 70°C) and cold water, safe and explosion-proof, and has a long service life. ????Low water pressure protection: The Water Flow Switch return spring is made of high-quality stainless steel. When the water pressure is >0.03KG, the water pump can be started, so there is no need to worry about low water pressure. ????Switch principle: Water Flow Switch uses a water flow magnetic control device and a switch control sensing element to control the opening or closing of the water pump, which is very convenient. (If you have any questions, please feel free to ~) ????Widely used: Water Flow Switch is widely used in households in low-pressure areas, especially for low water pressure ignition start of water heaters and automatic water circulation of solar water heaters. 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 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.
