Q1. Do solenoid valves fail open or closed?
Normally closed or normally open refers to the position of the solenoid when the coil is de-energized. A normally closed solenoid will block the air supply from the actuator when the coil is de-energized. Normally open solenoids allow an open path for the air supply to reach the actuator when the coil is de-energized.
Q2. Solenoid valve doesn't open / close properly?
Check power supply and make sure voltage and frequency are correct. Also check the connections. Check if flow direction matches with the indicators on the valve body or matches within limits as specified in the valve manual.
Q3. What the most common solenoid valve problems?
Common solenoid problems include plungers that are stuck either in or out, attached valves that are frozen in place, bad internal coil windings, and excessive noise during operation. Some of these problems are the result of internal solenoid issues, while others are typically caused by external components.
Q4. When should a solenoid valve be replaced?
As a general rule of thumb, if your solenoid valve show signs of wear or damage, then it is likely time for a replacement.
Q5. Solenoid valve troubleshoot
Check if the power supply is correct and the coil can dissipate heat by ventilation. Install a new coil and never power the coil when not mounted on the valve. Check for moisture within and replace if necessary. Replace any damaged or bent armatures as well, and check media compatibility with your valve.
