Troubleshooting and Maintenance: Ensuring Reliability with AirTAC Solenoid Valves in Packaging Machines

A packaging machine's reliability is directly tied to its production line's uptime. AirTAC solenoid valves are known for their high reliability, but in high-intensity work environments, proper troubleshooting and maintenance are still necessary to ensure stable operation. This article provides a practical troubleshooting guide to help technicians quickly find and fix problems.

• Quick Troubleshooting for Common Problems:

  • Valve won't actuate: First, check if the power voltage is correct and if the coil is energized. Then, check if the air pressure meets the valve's minimum operating pressure. Finally, try the manual override button. If the valve works manually, the problem is likely with the coil or electrical circuit. If it's stuck, it could be due to internal debris or a mechanical fault.

  • Air leak: Check the valve body, exhaust ports, and all tubing connections. Use soapy water or a professional leak detector to find small leaks. Leaks are usually caused by worn seals or loose connections, so replace the seals or tighten the connections.

  • Loud noise: Check for stable power voltage. For AC coils, an unstable voltage can cause loud humming.

• Preventive Maintenance: Regularly inspect your FRL (Filter, Regulator, Lubricator) unit to ensure the filter is clean, the drain is working, and the lubricant is sufficient. Clean compressed air is key to extending the solenoid valve's life. In dusty environments, install exhaust silencers and filters to prevent dust from getting into the valve body.

• Modularity and Quick Replacement: AirTAC's manifold design makes replacing individual valves extremely convenient. When a single valve fails, you don't need to disassemble all the tubing and wiring; you simply replace the faulty valve, minimizing downtime and getting production back up and running fast.
