Keeping an industrial gas solenoid valve working well is mostly about clean gas, correct operation, and regular checks. Here’s a practical, no-nonsense guide you can actually use in the field 👇

1. Keep the Gas Clean (This Is Critical)

Dirty gas is the #1 killer of solenoid valves.

• Install a gas filter/strainer upstream of the valve

• Clean or replace the filter regularly (don’t wait for problems)

• Blow down the gas line before installing a new valve

👉 If debris reaches the valve seat, it won’t close tightly → gas leakage risk.

2. Use the Correct Electrical Supply

Wrong voltage = overheated coil = early failure.

• Match coil voltage & frequency exactly (e.g. 220VAC 50Hz, 24VDC)

• Keep voltage within ±10% of rated value

• Ensure good grounding and tight wiring connections

🔥 Overvoltage burns coils; undervoltage causes weak opening.

3. Control Operating Pressure & Flow

Solenoid valves are not “one-size-fits-all”.

• Operate within the valve’s rated pressure range

• Avoid sudden pressure shocks

• Don’t oversize the valve (too large = unstable control)

📌 Always check minimum & maximum pressure requirements.

4. Install It Correctly

Bad installation causes good valves to fail.

• Follow flow direction arrow

• Mount in recommended position (often horizontal coil upright)

• Leave enough space for maintenance and coil removal

🚫 Avoid installing where vibration or heat is excessive.

5. Keep Temperature Under Control

Heat kills seals and coils.

• Keep ambient temperature within valve limits

• Avoid direct exposure to burner flame or radiant heat

• Use heat shields if needed near combustion equipment

6. Cycle the Valve Properly

Solenoid valves don’t like abuse.

• Avoid excessive ON/OFF cycling beyond design limits

• For high-frequency control, use proportional valves, not solenoids

• Let the valve cool if operating continuously

7. Do Regular Inspections

A simple checklist saves shutdowns:

• Listen for abnormal noise (buzzing, clicking)

• Check for gas leaks at joints and valve body

• Measure coil resistance occasionally

• Verify fast opening and tight closing

🛠 Replace worn seals or weak coils early—don’t wait for failure.

8. Keep Spare Parts Ready

For critical gas systems:

• Keep spare coils, seals, or a complete valve

• Label valves with installation date and specs

• Record maintenance history
