Valve Open when de-energized, water goes through. Recommend to use NO valve if open a long time, and shut down for a short time .

- Please select the valve’s bore size and Operation Mode matches the system efficiently, avoiding any issues like leakaging, insufficient water flow, increased energy consumption, or equipment damage .
- Regular Inspection and Cleaning the Electric Solenoid Valves, Proper maintenance ensures long-term stability and extends service life.
- Exterior Cleaning Frequency: Clean every 3–6 months, the more frequent in dusty or corrosive environments. Dry thoroughly with a clean cloth to prevent moisture-induced corrosion
- If valve can not work , please try to check as belows:
- 1. Please re-connect power supply wiring .
- 2. Please confirm if power supply voltage is within the operating range.
- 3. Please check whether the coil is desoldered or short circuit, Please replace the coil if defective.
- 4. If Fluid temperature is too high, please replace the appropriate solenoid valve.
- 5. Please check if any impurities makes valve spool stuck , or sealing damage should be replaced.
- 6. Liquid viscosity is too large, too high frequency and life has end to make a replacement in time.
