To keep an industrial gas solenoid valve working well and lasting a long time, focus on clean gas, correct operation, and regular maintenance.

1. Keep the Gas Clean (Most Important)

Dirty gas is the #1 killer of solenoid valves.

• Install a gas filter/strainer upstream (usually 50–100 mesh)

• Clean or replace the filter regularly

• Drain condensate (water/oil) from the gas line

• Make sure pipe scale and welding slag are removed before commissioning

👉 Clean gas = stable opening + tight shutoff

2. Use the Correct Valve

Make sure the valve matches your system:

• Correct gas type (natural gas, LPG, biogas, etc.)

• Correct pressure range (don’t exceed max pressure)

• Correct voltage (AC/DC, 24V / 110V / 220V)

• Normally Closed (NC) or Normally Open (NO) as required

• Explosion-proof rating if used in hazardous areas

Wrong selection = overheating, slow response, or coil burnout.

3. Proper Installation

Bad installation causes many early failures.

• Install in the direction of flow arrow

• Mount vertically if manufacturer recommends it

• Support the pipeline to avoid stress on the valve body

• Keep coil away from excessive heat (>80–90°C unless rated)

• Use proper sealing (no excess tape entering the valve)

4. Protect the Solenoid Coil

The coil is sensitive.

• Ensure stable power supply (no voltage fluctuation)

• Check coil temperature during operation

• Avoid continuous energizing beyond design limits

• Replace coils showing discoloration or burning smell

💡 A hot coil today is a failed coil tomorrow.

5. Regular Inspection & Testing

Set a simple maintenance routine:

• Weekly/monthly:

  • Check for gas leakage

  • Listen for abnormal buzzing or delayed action

• Quarterly:

  • Test open/close response time

  • Clean valve internals if allowed

• Annually:

  • Replace seals, O-rings, or diaphragm (if applicable)

6. Prevent Frequent On–Off Cycling

Excessive switching shortens valve life.

• Use control logic or timers to reduce rapid cycling

• For high-frequency control, consider:

  • Proportional valve

  • Motorized valve

  • Valve rated for high cycling

7. Keep Environment Friendly

• Protect from dust, moisture, and corrosive gases

• Use IP-rated or weatherproof coils outdoors

• Avoid vibration or shock near the valve

8. Act Fast on Early Symptoms

Replace or service the valve if you notice:

• Slow opening or closing

• Valve stuck open or closed

• Gas leakage when closed

• Coil overheating or noise

Ignoring small problems often leads to safety shutdowns or burner trips.
