Ekgas, keeping a solenoid valve working well depends on correct selection, proper installation, and regular maintenance. Here’s a practical, industry-friendly guide—especially relevant for gas, air, steam, or liquid systems.

1. Choose the Right Solenoid Valve

Before installation, make sure the valve matches your application:

• Correct medium (gas, air, water, oil, steam)

• Pressure range (min & max working pressure)

• Voltage & frequency (AC/DC, 50/60Hz)

• Temperature limits

• Normally Open (NO) or Normally Closed (NC) type

 Using the wrong valve is the most common cause of early failure.

2. Install It Correctly

Proper installation greatly extends service life:

• Install in the correct flow direction (follow the arrow on the valve body)

• Keep the coil upright (vertical) when possible

• Avoid pipe stress—use proper pipe alignment

• Seal threads correctly to prevent leaks

• Ensure wiring is done according to the rated voltage

3. Keep the Fluid Clean

Contamination is the #1 enemy of solenoid valves:

• Install a filter or strainer upstream

• Regularly clean or replace the filter

• Avoid rust, debris, oil sludge, or moisture entering the valve

 Clean media = smooth valve movement

4. Prevent Coil Overheating

The solenoid coil must stay within safe limits:

• Do not exceed rated voltage (overvoltage overheats the coil)

• Ensure good ventilation around the coil

• Avoid continuous energization if the valve is not designed for it

• Check coil temperature during operation

 Overheating shortens coil life dramatically.

5. Perform Regular Inspections

Set up a simple maintenance routine:

• Check for leakage at seals and joints

• Listen for abnormal noise or buzzing

• Verify fast opening/closing response

• Inspect wiring connections for looseness or corrosion

6. Clean Internal Parts Periodically

If performance drops:

• Power off and depressurize the system

• Remove the valve and clean:

  • Plunger

  • Core tube

  • Seals

• Use suitable cleaning agents (no harsh chemicals)

 Never scratch the plunger or core surface.

7. Protect from Harsh Environments

Environmental factors matter:

• Use IP-rated coils for dusty or wet areas

• Protect from rain, vibration, and corrosive gases

• In cold environments, prevent freezing

• In hot zones, use heat-resistant coils

8. Replace Wear Parts on Time

Some parts naturally wear out:

• Seals

• Springs

• Coil (after long service hours)

Replacing small parts early prevents system shutdowns.

9. Keep Spare Valves or Coils

For critical systems:

• Keep spare coils or complete valves

• Label voltage and valve type clearly

• This reduces downtime during emergencies
