Plastic Solenoid Valve 12V 220V RO Water 3/8" Quick Plug
Plastic Solenoid Valve 12V 220V RO Water 3/8" Quick Plug
Details
Plastic Solenoid Valve for RO Systems, Drinking Fountains & Pipeline Machines
Take precise control of your water flow with this durable plastic solenoid valve. Engineered for use with reverse osmosis (RO) systems, drinking water dispensers, and in-line pipeline machines, this valve delivers reliable, automated water control with a simple electrical signal. Available in 12V DC and 220V AC versions, it features a 3/8" (9.5mm) quick-plug tube connection for fast, tool-free installation.
⚠️ Important Notes:
- 220V Non-pressure Type: May produce some noise and vibration during operation — please consider this before ordering.
- Custom Voltages Available: AC110V, AC24V, AC12V, DC6V — contact us for special orders.
Valve Types
- 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 MPa (up to 0.02 MPa). No filter included.

Frequently Asked Questions
Q: What is the difference between the Normally Closed (NC) and Normally Open (NO) solenoid valve configurations?
A: A Normally Closed (NC) solenoid valve keeps the water flow OFF when no power is applied — energizing it (powering on) opens the valve and allows water to flow. This is the most commonly used configuration. A Normally Open (NO) valve works in reverse — water flows freely when there is no power, and energizing the coil shuts the flow off. Choose NC for standard water dispensers and RO systems, and NO for applications that require water flow to stop upon activation.
Q: Is this solenoid valve compatible with my RO (reverse osmosis) water purifier?
A: Yes. This plastic solenoid valve is specifically designed for use with RO (reverse osmosis) machines, drinking water dispensers, and in-line pipeline systems. It supports purified and drinking water media, features a standard 3/8" (9.5mm) quick-plug tube connection, and is available in DC 12V — the voltage most commonly used by RO systems. Be sure to match the pressure type (Inlet Valve) or non-pressure type (Drain Valve) to your specific application.
Q: Can I get this valve in a voltage other than 12V or 220V?
A: The standard in-stock options are DC 12V and AC 220V. However, custom voltages including AC 110V, AC 24V, AC 12V, and DC 6V can be arranged — simply contact us before placing your order to discuss your requirements.
Q: Will the 220V version make noise during operation?
A: The 220V non-pressure type version may produce some audible noise and slight vibration during operation. This is a known characteristic of this valve type at that voltage. If a quiet installation environment is important, we recommend considering the DC 12V version or contacting us to discuss the best option for your setup.
