⚠️ Symptoms of a Failing Solenoid Valve
Common signs that the solenoid or internal components may need replacement:
-
⚠️ Valve fails to open or close
-
⚠️ Buzzing or loud humming from coil
-
⚠️ Overheating coil or burning smell
-
⚠️ System pressure not holding or reduced flow
-
⚠️ Leaks around diaphragm or body
-
⚠️ Valve sticking intermittently during operation
-
⚠️ Erratic cycling or delayed actuation
Replace the valve or coil if these symptoms persist.
❓ Frequently Asked Questions
Q: Can this valve be used with steam?
A: It can handle slightly aggressive media and low-temperature steam, but for high-temperature steam applications a different model is recommended.
Q: Is the coil waterproof?
A: Yes—NEMA 4X housing provides protection against dust, water spray, and corrosion.
Q: Can this valve be mounted horizontally?
A: No. It must be mounted vertical and upright for proper operation.
Q: Is this valve safe for natural gas?
A: Yes. It is approved for air and neutral gases up to 200 PSI.
Q: Does it come with a coil?
A: Yes, this part number includes the 120V AC coil.
🛒 Shopping Tips
-
Make sure your system requires a 1-1/2" NPT normally closed solenoid valve
-
Verify pressure requirements (Air/Gas: 200 PSI max, Water: 150 PSI max)
-
Ensure mounting orientation is vertical
-
Check fluid type (compatible with air, gas, water, light oil)
-
Confirm voltage: 110/120V AC
-
For continuous duty use, ensure coil cooling is adequate
