Electric Solenoid Valve | 2inch for Water Air Gas
Blog Article
Here's a detailed breakdown of the 2-inch Electric Solenoid Valve for water, air, and gas applications:
Key Specifications
Valve Size: 2" (DN50)
Connection Type: Threaded (NPT, BSP) or Flanged (ANSI/ISO standards)
Media Compatibility:
Water (potable, industrial)
Air (compressed/pneumatic systems)
Gas (natural gas, propane; requires explosion-proof models for hazardous areas)
Voltage Options:
AC: 24V, 110V, 220V, 380V
DC: 12V, 24V
Pressure Range:
Water/Air: 0–10 bar (standard)
Gas: 0–4 bar (requires tight sealing)
Temperature Range:
Standard: -10°C to +80°C
High-Temp: Up to +120°C (with EPDM/Viton seals)
Types & Operation
Type | Function | Best For |
---|---|---|
Normally Closed (NC) | Opens when energized | Most water/gas systems |
Normally Open (NO) | Closes when energized | Safety shutoff applications |
Bi-Stable | Holds position without power | Energy-saving setups |
Materials & Seals
Body: Brass (water/air), Stainless Steel (corrosive media), PVC (chemicals)
Seals: NBR (standard), EPDM (high temp), PTFE (aggressive chemicals)
Coil: Class F/H insulation (for heat resistance)
Common Applications
Water: Irrigation, HVAC, industrial pipelines
Air: Pneumatic controls, dust collection systems
Gas: Burner control, fuel lines (requires ATEX/IECEx certification if explosive)
Wiring & Installation
Electrical:
Connect to power supply matching coil voltage (e.g., 220V AC).
Use solenoid-rated fuse (typically 1–5A).
Plumbing:
Install with arrow pointing in flow direction.
Use thread sealant (Teflon tape for NPT).
Maintenance:
Install strainer upstream for dirty media.
Periodically test manual override (if equipped).
Safety & Certifications
Water/NSF: NSF/ANSI 61 for potable water
Gas: ATEX Directive 2014/34/EU (Zone 1/2)
General: ISO 9001, CE, RoHS
Top Brands
ASCO (high-pressure industrial)
Bürkert (precision control)
SMC (pneumatics)
Danfoss (HVAC-focused)
Troubleshooting
❌ Valve doesn’t open:
Check power supply (measure coil voltage).
Listen for "click" (if silent, coil may be burnt).
❌ Leakage:
Inspect seals/diaphragm for wear.
Ensure proper pressure rating.
