Right-angled normally closed two-position three-position miniature solenoid valve installation notes: 1. The normally-closed, normally-closed, two-position, three-position miniature solenoid valve should be installed with care that the arrow on the valve body should be consistent with the flow direction of the medium. Do not install in places with direct dripping or splashing. Solenoid valve should be installed vertically upwards; 2. The solenoid valve should ensure normal operation within the range of 15%-10% fluctuation of the rated voltage of the power supply voltage; 3. After the solenoid valve is installed, there must be no reverse pressure difference in the pipeline. And need to be energized several times, so that it can be put into use after being properly warmed; 4. Thoroughly clean the pipeline before installing the solenoid valve. The medium should be free of impurities. Valve pre-filter; 5. When the solenoid valve is faulty or cleaned, the bypass device should be installed to ensure the system continues to operate.
