3. Operation Guide
-
Valve operation
- For normally closed valves
- When the coil is energized, the valve opens, connecting the inlet port (P) with working port (A)
- When the coil is de-energized, the valve closes, connecting the working port (A) with exhaust port (R)
- For normally open valves
- When the coil is energized, the valve closes, disconnecting the inlet port (P) from working port (A)
- When the coil is de-energized, the valve opens, connecting the inlet port (P) with working port (A)
- Remote control of the valve can be achieved through control signals
-
Working principle
- The solenoid valve controls the movement of the valve core through the energization and de-energization of the electromagnetic coils
- The movement of the valve core changes the connection method of the air circuit, thereby controlling the direction of fluid flow
- Adopting a direct-acting structure, it provides quick response and reliable operation
-
Notes
- Do not exceed the valve's maximum working pressure and temperature range
- Avoid use in environments with strong vibration or impact
- Keep the valve clean to prevent dust and impurities from entering the valve body
- Ensure stable power supply voltage to avoid excessive voltage fluctuations

4. Maintenance
-
Regular inspection
- Check for valve leakage
- Verify normal valve operation
- Ensure connections are secure
- Check that electrical connections are in good condition
-
Cleaning
- Regularly clean the external surface of the valve to remove dust and dirt
- If impurities are found inside the valve, clean them promptly
-
Lubrication
- Regularly add an appropriate amount of lubricating oil to the valve's moving parts
- Use lubricating oil compatible with the seals
-
Storage
- For long-term storage, store the valve in a dry, clean, and ventilated environment
- Avoid direct sunlight and high-temperature environments

5. Troubleshooting
-
Valve fails to operate
- Possible causes: Power failure or voltage mismatch, damaged coil, valve core stuck
- Solutions: Check power supply and voltage, replace the coil, clean or replace the valve core
-
Valve leakage
- Possible causes: Damaged seals, loose connections, damaged valve body
- Solutions: Replace seals, tighten connections, replace the valve body
-
