Electric Solenoid Valve | 2inch for Water Air Gas
Blog Article
The 2-inch Electric Solenoid Valve is an electromechanically controlled valve used to regulate the flow of water, air, or gas in industrial, irrigation, or pneumatic systems. Below are its key specifications and selection guidelines:
Key Features & Specifications
✅ Valve Size: 2 inches (DN50) – suitable for moderate to high flow rates.
✅ Voltage Options:
AC: 24V, 110V, 220V, 240V
DC: 12V, 24V (common for low-power applications).
✅ Media Compatibility:
Water (hot/cold), Air (compressed/pneumatic), Inert Gases (check material compatibility for corrosive gases).
✅ Pressure Range:
Water/Air: Typically 0–10 bar (145 PSI), high-pressure models up to 50 bar.
Gas: Lower pressure (1–5 bar) due to safety norms.
✅ Material:
Body: Brass (standard), Stainless Steel (corrosive/HT environments), PVC (chemical resistance).
Seal: NBR (nitrile rubber), EPDM (high temp), PTFE (chemical resistance).
✅ Operation Type:
Normally Closed (NC): Opens when powered (most common).
Normally Open (NO): Closes when powered.
✅ Temperature Range:
Standard: -10°C to +80°C (EPDM seals extend to +120°C).
Common Applications
Water: Irrigation, HVAC, water treatment, dishwasher/boiler systems.
Air: Pneumatic machinery, dust collection, compressor control.
Gas: Fuel lines (LPG/NG), industrial gas control (verify explosion-proof ratings).
Wiring & Installation
Power Supply: Match voltage (e.g., 220V AC solenoid → 220V AC supply).
Connection:
2-Wire: Basic on/off control (no polarity for AC).
3-Wire: Includes ground (for safety in humid environments).
Installation:
Arrow on valve body indicates flow direction.
Use thread sealant (Teflon tape) for leak-proof piping.
Popular Models & Brands

Troubleshooting
⚠ Valve Not Opening:
Check power supply/voltage.
Debris in valve? Disassemble and clean.
⚠ Leakage When Closed:
Worn/damaged seal (replace diaphragm or O-ring).
Incorrect pressure rating (overload damages seals).
⚠ Overheating Coil:
Use intermittent duty cycle (continuous power may require a latching solenoid).
Selection Tips
Gas Use: Opt for explosion-proof certifications (ATEX, UL) if handling flammable gases.
High Temp/Pressure: Choose stainless steel + PTFE seals.
Pulse Control? Use a latching solenoid (energy-efficient).https://store.unigulfsupply.com/product/electric-solenoid-valve-2inch-for-water-air-gas/
