SV (SOLENOID VALVE )

A solenoid valve (SV) for home-use Reverse Osmosis (RO) systems typically has specifications tailored for compact design, low power consumption, and compatibility with water filtration systems. Here are the typical specifications:

General Specifications

1. Type: Normally closed (NC) solenoid valve.
2. Material:
   • Body: Food-grade plastic (e.g., polypropylene) or brass for durability.
   • Seal: Nitrile rubber (NBR), EPDM, or Viton, suitable for water contact.
3. Port Size: Commonly 1/4" or 3/8" BSP or NPT threads, matching RO tubing.
4. Connection: Quick-connect fittings for easy installation.

Electrical Specifications

1. Voltage:
   • 24V DC (common in RO systems).
   • 12V DC (for smaller systems).
   • 110V/220V AC options available.
2. Power Consumption: Low, typically around 5-10W.
3. Coil Resistance: As per the voltage rating, ensuring compatibility with the RO system power supply.

Performance Specifications

1. Working Pressure:
   • Minimum: 0.02 MPa (3 psi).
   • Maximum: 0.8 MPa (116 psi).
2. Flow Rate: Depends on the system; typically 1-3 liters per minute.
3. Temperature Range: 0°C to 50°C (32°F to 122°F), suitable for household water.
4. Operating Medium: Clean water or treated water.

Certifications

• CE Certification: For electrical safety.
• RoHS Compliance: Ensures materials are safe and environmentally friendly.
• NSF/ANSI Certification: For drinking water safety (if applicable).

Typical Applications in RO Systems

• Automatic control of water flow during the filtration process.
• Prevents water backflow.
• Works in tandem with pressure switches and pumps for efficient operation.
