It is made of high-temperature resistant material, allowing the product to be used with hot water up to 70 degrees Celsius. The pump can start when the water pressure is 0.03 kg. It uses electronic components as the control device, ensuring safe operation without spark generation. This water flow switch features a water flow electromagnetic control system and on-off sensing elements for automatic pump control. The induction chamber, magnetic control chamber, and electronic components are separately designed to prevent failure due to magnetic attraction of iron particles in the pipeline. Constructed from high-quality plastic and metal materials, this flow switch is durable and reliable. It measures 7 cm in length and 5.2 cm in height. This water flow switch is widely used in residential low-pressure applications, particularly suitable for low water pressure ignition in water heaters and automatic water circulation in solar water heating systems.Item Name: Water Flow Switch Material: Plastic, Metal Supply Voltage: AC 220V Working Current: 0.5A Model: HT-60 Screw Thread: G1/2-inch - 1/2-inch Fluid Pressure: Medium Pressure 0.6MPa Medium Temperature: 70 Degrees Celsius Size Details: 7cm x 5.2cm / 2.76" x 2.05" (Approx.)Notes: Due to differences in lighting and screen settings, the item's color may vary slightly from the images.
