Solenoid valves are the core control switches of air compressors. Small valve failures often cause large-area production shutdowns. Many overseas buyers choose cheap general-purpose valves, resulting in frequent aging, jamming and air leakage.
How to Choose Correctly
Match the global voltage 220V/380V/415V to avoid coil burnout. Select high-temperature resistant rubber diaphragm materials to adapt to the high-temperature working environment of the compressor. The working pressure must reach 1.6MPa industrial grade to ensure stable switching.
Maintenance Rules
Regularly clean the valve body impurities every 3 months to prevent dust and oil sludge from blocking the valve port. Check the diaphragm aging degree. If slow loading or residual air leakage occurs, replace the diaphragm in time. Avoid long-term power-on standby, which will cause coil overheating and burnout.
Standard selection and maintenance can extend the valve service life to more than 2 years and eliminate common faults such as no loading, constant unloading and pressure failure.
