220V 1/2 inch Solenoid Valve – Automated fluid control with solid brass body and NBR sealing
Looking to automate your water supply, control compressed air, or shut off oil flow without manual intervention? This 220V solenoid valve with a 1/2 inch thread does exactly that—simply, reliably, and without leaks. It mounts directly onto your existing pipework and integrates seamlessly with any control source, such as a timer, irrigation controller, or PLC.
Note: The solenoid valve opens automatically when 220V AC power is applied and closes tightly when the power is cut. Please check the flow direction indicated by the arrow on the valve body before installation.
Why choose this model? (Key benefits):
- Solid brass body — Offers superior resistance to corrosion and pressure compared to zinc or plastic alternatives, ensuring no cracking after years of use.
- NBR sealing tested to 80°C — The gaskets remain durable and leak-free when used with hot water, compressed air, or non-corrosive oils.
- Maximum pressure of 10 bar (1 MPa) — Capable of handling demanding technical installations, including industrial systems.
- Standard 1/2 inch BSP thread — Screws directly onto existing pipes without the need for extra adapters or modifications.
- Low 17W power consumption — Efficient enough for continuous operation without significantly impacting your electricity bills.
- Power-failure safety — The normally closed design ensures that if the power cuts out, the valve automatically shuts off the flow.
Details and Performance
The electromagnetic pilot mechanism actuates the internal diaphragm in less than a second once power is applied. The copper coil generates a stable magnetic field, preventing overheating during continuous operation. The 16 mm flow diameter ensures a generous flow rate without pressure drops that could affect the rest of your system.

Usage Instructions
- Identify the flow direction by following the arrow engraved on the body and install the solenoid valve onto the pipe accordingly.
- Connect the power wires to a 220V AC source via a relay, timer, or automatic controller (e.g., irrigation controller, PLC).
- Ensure the system pressure does not exceed 1 MPa (10 bar) and that the fluid temperature remains between -5°C and +80°C.
- When voltage is applied, the valve opens automatically; when the power is cut, the internal spring returns it to a tightly closed position.
- For outdoor use or in damp environments, protect the coil and electrical connections with a suitable waterproof housing.

Frequently Asked Questions
Does it work with hot water?
Yes. The brass body and NBR seal can withstand temperatures of up to 80°C without degrading the gaskets or causing leaks.
What happens if the power goes out?
The valve is normally closed: the internal spring automatically blocks the flow in the absence of power. No manual intervention is required to prevent leaks.
Can I use it for automatic irrigation?
Yes, this is one of its most common applications. When connected to a timer or irrigation controller, it automatically manages water supply across different zones without supervision.
Is it compatible only with water or other fluids too?
It works with water, compressed air, and non-corrosive oils, within the 10 bar pressure limit. It is not recommended for corrosive, acidic, or flammable fluids.
