Keeping an industrial gas solenoid valve working well is mostly about clean gas, correct operation, and regular checks. Since you’re dealing with combustion systems a lot, I’ll keep this practical and field-tested 👇

1. Keep the Gas Clean (Most Important)

Dirty gas is the #1 killer of solenoid valves.

• ✅ Install a gas filter upstream (usually 40–100 μm)

• 🔄 Clean or replace the filter regularly

• 🚫 Prevent rust, welding slag, oil, and dust from entering the line

• ⚠️ After new pipeline installation, blow the line clean before connecting the valve

👉 Even a perfect solenoid valve will fail quickly with dirty gas.

2. Operate Within Rated Conditions

Never push a solenoid valve beyond its design limits.

• Gas type: natural gas, LPG, biogas, etc. (must match valve approval)

• Pressure range: not too high, not too low

• Temperature: ambient and gas temperature within spec

• Flow direction: follow the arrow on the valve body

⚠️ Low pressure is a common problem—many valves need a minimum pressure differential to open fully.

3. Electrical Power Care

Solenoid coils are sensitive.

• 🔌 Use correct voltage and frequency (e.g. 230VAC, 24VDC)

• ⚡ Keep voltage stable (±10% max)

• 🧯 Ensure good grounding

• 🕒 Avoid continuous energizing beyond the valve’s duty rating (unless it’s designed for it)

🔥 Overheating coils = shortened life.

4. Regular Inspection & Testing

Create a simple routine—monthly or quarterly.

Check:

• 👂 Abnormal noise or vibration

• 👃 Gas leakage (use gas detector or soap test)

• 🌡️ Coil temperature (hot is normal, too hot is not)

• 🧲 Response time (opening/closing delay)

👉 In burner safety systems, always do leak-tightness tests.

5. Clean Internal Parts (During Shutdown)

When the system is off and gas is isolated:

• Remove the valve carefully

• Clean plunger, core tube, and sealing surfaces

• ❌ Do NOT use abrasive tools

• ❌ Do NOT oil internal parts (unless manufacturer allows it)

If seals are worn → replace, don’t reuse.

6. Correct Installation Practices

Bad installation = early failure.

• Valve mounted in recommended orientation (often horizontal)

• Coil upright if specified

• Pipe stress not transferred to valve body

• Enough space for coil removal and maintenance

7. Use the Right Valve for the Job

Not all solenoid valves are the same.

• 🔥 Use safety shut-off valves (EN 161 / SIL rated) for burners

• ⏱️ Fast-closing type for safety

• 🧱 Explosion-proof coil if required

• 🧯 Normally-closed (NC) is standard for gas safety

8. Keep Spares & Records

• Keep spare coils and seal kits

• Record failures, replacement dates, and causes

• Patterns = early warning of system problems

Quick Rule of Thumb

Clean gas + correct pressure + stable power = long valve life
