Proportional soleniods: failure due to abuse
 |
As seen in other pictures, the sealing areas of solenoids can just wear out.
Testing a linear solenoid can burn up the coil in no time!
Adjustment features for the solenoid calibration at the factory are often unjustly altered. Some manufacturers have eliminated these features to prevent this from occurring.
