solenoid valve PM checklist

Ensure the power supply to the solenoid valve is turned off.

Wear appropriate personal protective equipment (PPE).

Follow lockout/tagout (LOTO) procedures.

Check for any visible signs of damage or wear on the solenoid valve.

Inspect for leaks around the valve body and connections.

Examine wiring and connectors for fraying or corrosion.

Apply power to the solenoid valve and check its operation.

Listen for unusual noises during operation.

Verify that the valve opens and closes fully without sticking.

Measure the voltage at the solenoid terminals to ensure it matches specifications.

Inspect the coil for signs of overheating or damage.

Confirm that all electrical connections are secure and free of corrosion.

Here are some additional steps you can include in the Electrical Inspection section of the solenoid valve PM checklist

Check the resistance of the solenoid coil with a multimeter to ensure it is within the manufacturer's specified range

Inspect the wiring harness for any signs of wear, fraying, or damage

Verify that the solenoid's polarity is correct, if applicable

Ensure that any protective covers or conduit are properly installed and not damaged

Test the operation of any associated control switches or relays to ensure they are functioning correctly

Check for any signs of moisture ingress or environmental damage to electrical components

Confirm that the solenoid operates correctly when energized and de-energized, with no unusual noises or vibrations

Ensure that any fuses or circuit breakers in the electrical supply are rated correctly and functioning properly

Clean the exterior of the solenoid valve with a suitable solvent.

Remove any debris or buildup from the valve body and surrounding area.

If applicable, clean or replace the filter or strainer.

Apply lubricant to any moving parts as per manufacturer recommendations.

Ensure that the lubricant is suitable for the operating environment.

Replace any worn or damaged components, such as seals or gaskets.

If necessary, replace the entire solenoid valve based on condition assessment.

Record all maintenance activities and findings in the maintenance log.

Note any parts replaced and date of service performed.

Schedule the next preventive maintenance check as per the maintenance plan.

Conduct a final visual inspection of the solenoid valve after maintenance.

Ensure all tools and materials are removed from the work area.

Re-energize the solenoid valve and monitor for proper operation.
