Installation Steps
-
Pre-installation Preparation
- Verify that the product model and specifications match system requirements
- Confirm that the power supply voltage matches the solenoid valve rating
- Ensure the medium is clean; a filter with 40μm or higher precision is recommended
- Remove impurities, oil contamination, and moisture from the pipeline
-
Installation Process
- Correctly connect the inlet port (P), working port (A/B), and exhaust port (R/S) according to the arrow indicator on the valve body
- Wrap PTFE tape in a clockwise direction, with wrapping length not exceeding 80% of the thread length
- Avoid excessive force during installation to prevent damage to the valve body and threads
- Ensure the coil is installed vertically upward; horizontal or inverted installation is not recommended
- Reserve sufficient maintenance space, with at least 100mm clearance above the coil
-
Electrical Connection
- Turn off the power supply before connecting wires according to the wiring diagram
- Ensure secure connections to prevent poor contact
- For explosion-proof models, comply with relevant explosion-proof standard requirements
- After wiring is complete, check insulation performance to ensure safety

Operation Guide
-
Initial Use
- Manually test valve core movement for flexibility before powering on
- Slowly open the air supply and check for leaks
- Gradually adjust the working pressure to the rated value
- Perform no-load testing to confirm normal solenoid valve operation
-
Normal Operation
- Ensure working pressure remains within the rated range
- Avoid frequent start-stop cycles to reduce unnecessary valve operations
- Regularly check operating status to ensure proper solenoid valve response
- Record operating parameters and establish maintenance records
-
Special Working Condition Handling
- Implement anti-freezing measures when used in low-temperature environments
- Enhance waterproof and moisture-proof measures in humid environments
- Take shock absorption measures in high-vibration applications
- Monitor coil temperature during high-frequency operations

Maintenance
-
Daily Maintenance
- Regularly clean the exterior of the valve body to maintain a clean surface
- Check for loose connections and tighten as necessary
- Observe the exhaust port for any abnormal conditions
- Record operating time and number of cycles
-
Periodic Maintenance
- Inspect the filter every 3 months and clean or replace the filter element as needed
- Check the condition of seals every 6 months and replace if aging is detected
- Conduct a comprehensive inspection annually, including coil insulation performance testing
- Adjust maintenance intervals based on usage frequency and environmental conditions
-
Long-term Storage
- Thoroughly clean the interior of the valve body before storage
- Disconnect power and air supply, and drain internal media
- Seal the interfaces to prevent dust ingress
- Store in a dry, well-ventilated environment away from direct sunlight
