Two Valve Types — Choose What You Need

• Pressure Type (Inlet Water Valve): Suitable for water pressure 0.02–0.8 MPa. Includes a built-in filter. Ideal for pressurized water supply lines.
• Non-Pressure Type (Drain Water Valve): Suitable for water pressure 0–0.02 MPa. No filter included. Ideal for draining and gravity-fed systems.

Note: AC 220V non-pressure type may produce audible noise and slight vibration during operation. Please consider this before purchasing.

Custom voltages (AC 110V, AC 24V, AC 12V, DC 6V) are available on request — contact us before ordering.

Frequently Asked Questions

Q: What is the difference between a Normally Closed (NC) and Normally Open (NO) solenoid valve?

A: A Normally Closed (NC) solenoid valve keeps water flow off when no power is applied, and opens the flow when energized — the most common configuration for on-demand water control. A Normally Open (NO) valve does the opposite: water flows freely when de-energized and stops when power is applied. Choose NC for standard inlet applications and NO for systems that need a fail-safe open flow.

Q: Can I use this solenoid valve with a standard home water supply?

A: Yes — the pressure type (inlet water valve) is rated for 0.02–0.8 MPa, which covers typical residential water supply pressures. The G1/2" thread (20mm) is a standard pipe fitting size. It is compatible with purified and drinking water but is not suitable for acidic, alkaline, or highly viscous liquids.

Q: Is the coil direction adjustable after installation?

A: Yes. The coil can be rotated relative to the valve body at 90°, 180°, 360°, or 720° angles, giving you flexibility to orient the electrical connection in the most convenient direction for your installation without affecting the valve's performance.

Q: What voltages are available, and can I order a custom voltage?

A: Standard in-stock voltages are DC 12V, DC 24V, and AC 220V. Custom voltages including AC 110V, AC 24V, AC 12V, and DC 6V can be manufactured on request — please contact us before placing your order to arrange a custom configuration.
