**Solenoid Valve Maintenance and Troubleshooting Guide** To ensure the proper operation and longevity of solenoid valves, it is recommended to assign a dedicated person or team responsible for their installation, use, and regular maintenance. Performing 1–2 rounds of scheduled maintenance per year is one of the most effective ways to maintain reliable performance and extend the service life of the valve. There are four common situations that may cause the solenoid valve to malfunction or reduce its lifespan: 1. **Change in the medium during operation** – This can affect the valve’s performance if the fluid properties differ from the original design specifications. 2. **Rust buildup** – Especially in systems where moisture is present, rust can lead to internal blockages and corrosion. 3. **Oxidation of compressor oil**, which can produce carbon deposits and other debris that mix with the piping system. 4. **Dust and other impurities in the pipeline** – These particles can clog the valve mechanism and prevent smooth operation. When installing a solenoid valve or reactivating it after a long period of inactivity, it is important to test the media flow several times before full operation to ensure everything works correctly. If the steam valve has been idle for an extended time, drain any condensate first, then perform a few test cycles to confirm normal operation before resuming use. Before performing any maintenance, always disconnect the power supply and release any residual pressure in the system to avoid injury or damage. Do not disassemble the coil assembly unless absolutely necessary. If cleaning is required, you may use kerosene or trichloroethylene, but be cautious as these solvents may cause rubber components to swell. Replace any damaged or swollen rubber parts accordingly. When disassembling the valve for cleaning, keep all parts organized so they can be reassembled correctly. Follow the manufacturer's instructions carefully to avoid misalignment or improper installation. Our company provides wearing parts for certain models. If you need replacements, please refer to the instruction manual when placing your order. If you have any questions about the dismantling process, wearing parts, or other related matters, feel free to contact our company or local office for assistance. --- **Failure Analysis and Troubleshooting Methods** - **Power does not operate**: - Check the power connection and ensure the voltage is within the acceptable range. - If the coil is shorted or burned out, replace it. - Reconnect the power line and adjust the voltage as needed. - **Valve cannot pass fluid**: - Verify that the working pressure and fluid viscosity/temperature meet the valve's specifications. - Check for impurities in the valve core or pilot valve. Install a pre-filter if necessary. - Clean the filter or pilot valve holes. Consider replacing the product if the issue persists. - **Fluid cannot be shut off when the valve is closed**: - Ensure the fluid temperature and viscosity match the valve's requirements. - Inspect the spring for deformation or wear. Replace if necessary. - Check the valve seat and gasket for damage or adhesion. Clean or replace as needed. - Avoid overuse and consider replacing the valve if it has reached the end of its life. - **Leakage at pipe connections**: - Tighten bolts or replace damaged threads. - Replace seals if they are worn or damaged. - Ensure the fluid temperature is within acceptable limits. - Clean or replace the pilot seat, main seat, and sealing components if necessary. - **Excessive noise when energized**: - Check for loose fasteners and tighten them if needed. - Ensure the voltage and pressure are within the allowable range. - Adjust the pressure or differential pressure, or replace the valve if it doesn’t match the fluid characteristics. - Clean the armature suction surface to remove any foreign particles. Regular maintenance, careful operation, and prompt troubleshooting can significantly improve the performance and durability of solenoid valves. Always follow the manufacturer's guidelines and consult technical support when in doubt.
