👉 Wrong selection leads to: ❗ Leakage ❗ Performance loss ❗ Valve failure
⚙️ Engineering Perspective (Real Technical Depth) 🔹 Operating Principle Solenoid valves use electromagnetic force to move the plunger, opening or closing the flow.
👉 Two main types:
Direct acting → low pressure / low flow
Pilot operated → high flow / high pressure
🔹 Cv (Flow Coefficient) and Orifice Selection Valve capacity is determined by Cv value:
Low Cv → low flow
High Cv → high flow
✔ Incorrect Cv selection: ❗ Insufficient flow ❗ Pressure loss
🔹 Coil Duty Cycle (Critical but often overlooked) Coil operating type:
Continuous duty (ED100%)
Intermittent duty
👉 Wrong selection: ❗ Coil burnout ❗ Overheating
🔹 Pressure Differential (ΔP) Critical for pilot valves: 👉 Minimum pressure differential required
✔ If ΔP is insufficient: ❗ Valve does not open
⚠️ Failure Analysis (SEO + Engineering Advantage) 🔹 “Solenoid valve does not open” Cause:
Coil failure
Insufficient ΔP
Blockage
Solution: ✔ Coil check ✔ Pressure analysis ✔ Cleaning
🔹 “Valve leaking” Cause:
Seal wear
Dirt / particles
Solution: ✔ Seal kit replacement ✔ Filtration
🔹 “Coil burning” Cause:
Wrong voltage
Using intermittent duty instead of continuous
Solution: ✔ Correct coil selection ✔ Duty cycle check
