In industrial facilities, solenoid valves are critical components that control the flow of water, steam, gas, and chemical fluids by opening and closing within milliseconds. However, this fast operating principle also makes them one of the most sensitive and failure-prone pieces of equipment.
Especially:
- Food production lines
- Steam systems
- HVAC applications
- Automation facilities
In areas such as food production lines, steam systems, HVAC applications, and automation facilities, a single solenoid valve failure can bring the entire production line to a halt.
Most Common Solenoid Valve Failures
- Valve Does Not Open or Does Not Close
This condition is usually caused by:
- coil burnout
- power supply issue
- internal mechanical jamming
due to these reasons.
In particular, voltage fluctuations significantly shorten the coil’s lifespan.
- Stuck Open or Stuck Closed Issue
These types of failures are usually caused by:
- diaphragm damage
- spring deformation
- internal contamination
are caused by these factors.
This situation in the system leads to:
- pressure imbalance
- energy loss
- decline in product quality
and similar consequences.
- Leakage Problems
Leakage is one of the most dangerous failures because:
- it takes time to be noticed,
- it increases energy costs,
- it creates a safety risk,
Main causes are:
- gasket wear,
- high temperature exposure,
- chemical incompatibility,
- Noisy Operation (Vibration & Noise)
Vibration or noise coming from a solenoid valve is usually caused by:
- use of AC coil,
- loose mounting,
- pressure fluctuations,
are associated with.
This condition is a warning sign of more serious failures in the long term.
Main Causes of Solenoid Valve Failures
Incorrect Product Selection
t is one of the most common mistakes.
- incorrect pressure range,
- unsuitable fluid type,
- incorrect temperature selection,
Result: The valve’s lifespan can be reduced by up to 50%.
Electrical Problems
- low voltage,
- high voltage,
- fluctuating current,
About 70% of coil burnouts are caused by these issues.
Fluid Contamination
In systems where no filters are used:
- sediment,
- metal particles,
- limescale,
damage the internal mechanism of the valve.
Excessive Temperature
Especially in steam systems:
- diaphragm deformation,
- gasket damage due to overheating
It is very common.
How Can Solenoid Valve Failures Be Prevented?
- Correct Product Selection
- Valve suitable for the pressure rating
- Material suitable for the fluid type
- Heat-resistant structure
This step prevents 60% of failures from the outset.
- Use of Filtration
Installing a filter before the valve:
- It prevents clogging.
- It extends the mechanical lifespan.
- Periodic Maintenance Plan
Recommended maintenance interval:
- Heavy use: 3 months
- Standard use: 6 months
Items to check during maintenance:
- Coil condition
- gasket wear,
- Internal cleaning
- Voltage Stabilization
Use of a regulator:
- It prevents coil burnout.
- It increases system safety.
Tips to Double the Lifespan of a Solenoid Valve
- Dry running should be avoided.
- Choose an appropriate IP protection rating.
- Use original spare parts.
- Pay attention to the installation direction.
Conclusion: Don’t Wait for Failure—Prevent It
Solenoid valves are small but highly impactful equipment.
With the right selection + regular maintenance:
✔ You reduce production downtime
✔ You lower energy costs
✔ You increase system efficiency
