How To Detect Solenoid Valve Circuit

1. Solenoid valve working voltage waveform detection;

2. Solenoid valve resistance detection;

3. Detection of solenoid valve connection lines;

4. Solenoid valve power supply detection;

5. Solenoid valve mechanical failure detection

The flexibility check of the solenoid valve action can be carried out through the energization test. When the solenoid valve is energized with the battery voltage, a crisp opening and closing action sound should be heard. Otherwise, the action is not flexible, and the solenoid valve should be cleaned or replaced.

There are two types of solenoid valves: normally open (closed when energized) and normally closed (open when energized).
