How do I choose the correct voltage and port size for my project?

You need to match the valve's voltage to your power supply, so choose 12V or 24V DC for low-voltage systems, or 220V AC for mains power. The port size, either 1/2" or 3/4", should match the BSP fittings on your pipework. Be sure to select the right combination from the product options.

What does 'Normally Closed' mean for this valve?

'Normally Closed' (NC) means the valve stays shut and blocks flow when it has no power. When you send power to it, the solenoid activates and opens the valve, letting water or air pass through. It will close again as soon as the power is cut.

Is this plastic valve suitable for hot water or drinking water?

This valve is designed for use with media at normal temperatures, so it is not suitable for hot water systems. As it does not have a food-grade or WRAS approval, we do not recommend using it for drinking water. It's best for general purpose water or air control, like in irrigation systems.

This plastic solenoid valve works as an automatic, electric switch for air or water. It stays shut until it gets power. This stops unwanted flow. It comes in different voltages (12V DC, 24V DC, 220V AC) and port sizes (1/2", 3/4"). Features and Benefits - Made with a molded plastic body - It resists rust and mineral buildup. This makes it good for water systems and wet places. - Normally Closed (N/C) design - It stops flow if the power goes out. This is important for many control setups. - Standard 1/2" and 3/4" NPT threads - It connects directly to common pipes and fittings. You don't need adapters. - Different voltage choices - Pick the 12V or 24V plastic solenoid valve for low-voltage circuits. Or choose the 220V version for home appliances. Applications - Irrigation Systems - Use it to water different areas in gardens, lawns, or greenhouses automatically. - Water Purification Systems - It controls water flow in RO systems or other multi-stage filters. - DIY Projects - Build custom liquid dispensers, automatic aquarium top-off systems, or simple air controls.
