Video: Troubleshooting a Maxon Shutoff Valve

We understand the inconvenience that comes with having to send an instrument out for repair, so at Lesman we try to help you determine what’s wrong with your device before you remove it from service. After all, we don’t want you to lose any uptime if it’s something that can be fixed in the field.

Earlier this year, our combustion specialist put together a blogpost with sound clips that can help you identify which electrical component of your Maxon shutoff valve has failed.

Now, he’s put together a video to further help you diagnose these problems.

DISCLAIMER: If you are testing a valve installed within a line that you suspect is not functioning properly, you MUST make sure that the gas supply entering the fuel train is manually closed and locked-out. If the valve in question is failing in the energized state, shutdown your system IMMEDIATELY and remove the valve from service.

Each Maxon automatic reset shutoff valve comes with three critical electrical components (solenoid, motor, position switch) that need to work together for the valve to operate properly. By listening to the valve cycle to its energized state, you can detect if any of these critical electrical components needs to be replaced.

To learn more about Maxon Shutoff Valves, visit our website or give us a call. We are happy to help!
