It is made of high temperature resistant material so that the product can be used for hot water (up to 70 degrees Celsius). The pump can be started when the water pressure is 0.03KG. Adopting electronic components as the control device, it is very safe as no sparks are generated during operation.This water flow switch uses water flow electromagnetic control device and on-off control sensing elements to achieve automatic control of pump. The induction chamber, magnetic control chamber and electronic components are designed separately in order to avoid switch failure caused by magnetic adsorption of iron in the pipeline.With high-quality plastic and metal material, this flow switch is durable to use.It is 7cm long and 5.2cm high.This water flow switch 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.Item Name: Water Flow SwitchMaterial: Plastic, MetalSupply Voltage: AC 220VWorking Current: 0.5AModel: HT-60Screw Thread: G1/2-inch - 1/2-inchFluid Pressure: Medium Pressure 0.6mpaMedium Temperature: 70 Degree CelsiusSize Details: Size: 7cm x 5.2cm/2.76" x 2.05" (Approx.)Notes:Due to the light and screen setting difference, the item's color may be slightly different from the pictures.Please allow slight dimension difference due to different manual measurement.Package Includes:1 x Water Flow Switch2 x Gaskets Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
