12V/24V Inlet Solenoid Valve – RO Water Purifier Quick Connect

12V / 24V Inlet Solenoid Valve for Reverse Osmosis & Water Purifiers

Upgrade or repair your home water purification system with this precision-engineered DC inlet solenoid valve. Available in both DC 12V (Style A) and DC 24V (Style B) configurations, this valve is a perfect fit for reverse osmosis (RO) systems, pure water machines, tea makers, and water filtration setups that use standard 2-point (1/4") quick-connect tubing with an outer diameter of approximately 6.4 mm — no threading or special tools required.

Made in Mainland China.

Frequently Asked Questions

Q: What is the difference between Style A (12V) and Style B (24V) solenoid valves?

A: Style A is a DC 12V normally closed solenoid valve — meaning it stays closed when not powered and opens when electricity is applied. It's ideal for 12V RO systems and tea-table water purifiers. Style B is a DC 24V normally open valve — it stays open when unpowered and closes when energized. Choose the style that matches both your system's voltage and the open/close logic your application requires.

Q: What tubing size is compatible with this solenoid valve's quick-connect ports?

A: The valve uses standard 2-part (1/4") quick-connect fittings that accept tubing with an outer diameter of approximately 6.4 mm. Simply push the tubing into the port — no threading, wrenches, or additional fittings needed for a secure connection.

Q: Can this valve be used with a standard reverse osmosis (RO) home water purifier?

A: Yes. This inlet solenoid valve is specifically designed for use with reverse osmosis water purifiers and pure water machines that operate on DC 12V or DC 24V. It controls water flow into the system and is a common replacement or upgrade part for home RO setups.

Q: How long will this solenoid valve last?

A: The Style A (12V) valve is rated for a service life of 500,000 or more switching cycles, making it an exceptionally durable component for continuous home or light commercial use. Style B is also built to high-quality standards with pressure resistance exceeding 2.5 MPa.
