Solenoid Valve RO Water Purifier DC 12V 24V AC 220V 1/4" N/C N/O

Solenoid Valve for RO Water Purifier Systems – DC 12V/24V & AC 220V

Keep your reverse osmosis (RO) or water purification system running at peak performance with this reliable solenoid valve. Compatible with DC 12V, DC 24V, and AC 220V power sources, this quick push-in connect valve features a 1/4" (6.5mm) port and is available in both Normally Closed (N/C) and Normally Open (N/O) configurations — making it a versatile replacement or upgrade for inlet and drain water valve applications.

Made in Mainland China.

⚠️ Important Notes:

• AC 220V non-pressure type may produce audible noise and minor vibration — please take note before ordering if this is a concern.
• Other voltages (AC 110V, AC 24V, AC 12V, DC 6V) are available by custom order — please contact us for details.

Valve Type Guide

• Pressure Type (Inlet Water Valve): Suitable for water pressure 0.02–0.8 MPa. Includes built-in filter.
• Non-Pressure Type (Drain Water Valve): Suitable for water pressure 0–0.01 (0–0.02) MPa. No built-in filter.

Key Features

• Dual Configuration: Normally Closed (N/C) — power on, water flows; Normally Open (N/O) — power on, water stops
• Quick Push-In Connection: 1/4" (6.5mm) pipe diameter for easy, tool-free installation
• Adjustable Coil Position: Coil angle adjustable 90°, 180°, 360°, 720° for flexible installation in tight spaces
• Long Service Life: Rated for 500,000 cycles (at 30°C, 10-second intervals)
• Safe for Drinking Water: Suitable for purified and drinking water; not for acid, base, or viscous liquids
• Plastic Construction: Lightweight yet durable for water system environments

Frequently Asked Questions

Q: What is the difference between the Normally Closed (N/C) and Normally Open (N/O) solenoid valve?

A: A Normally Closed (N/C) solenoid valve stays closed when no power is applied and opens when power is switched on — water flows only while energized. A Normally Open (N/O) valve does the opposite: it stays open without power and closes when energized. Choose N/C for inlet water valve applications and N/O for drain or shut-off functions in your RO system.

Q: What pipe size does this solenoid valve fit?

A: This solenoid valve is designed for a 1/4" (6.5mm) quick push-in connection, which is the standard tubing size used in most household RO water purifiers and water filtration systems.

Q: Can I use this solenoid valve with voltages other than DC 12V, DC 24V, or AC 220V?

A: Yes — voltages such as AC 110V, AC 24V, AC 12V, and DC 6V are available through custom order. Please contact us directly to arrange a custom voltage configuration before purchasing.

Q: Is this valve safe for use with drinking water?

A: Yes. This solenoid valve is suitable for purified water and drinking water applications. It is not recommended for use with acidic, alkaline, or thick/viscous liquids.
