220V AC Solenoid Valve with Copper Body – Reliable Automatic Control for Water and Compressed Air
Whether you are automating an irrigation system, a heating circuit, or a compressed air line, this 220V AC solenoid valve with a 3/4″ connection and robust copper body provides precise, hands-free flow control. Designed for consistent performance year-round, it handles pressure and temperature fluctuations with ease.
Note: For correct operation, please ensure the flow direction matches the arrow marked on the valve body. We recommend installing the valve with the solenoid coil in an upright, vertical position.
Why choose this model? (Key Benefits):
- Instant Response — Rapid switching between open/closed states at 220V AC, eliminating mechanical delays or sticking.
- Durable Copper Construction — Superior to plastic alternatives, this valve resists corrosion and handles pressures up to 10 bar and temperatures between -5°C and 100°C, making it ideal for hot water heating systems.
- Fail-Safe Normally Closed Design — In the event of a power failure, the valve automatically closes, preventing uncontrolled leaks or flooding.
- Standard 3/4″ Connection — Designed for easy integration into existing pipework without the need for complex adapters or modifications.
- Energy Efficient — With a power consumption of just 17W, it is suitable for continuous operation and works perfectly with timers or automated controllers.
- Versatile Fluid Compatibility — A single, robust device capable of handling both water (hot or cold) and compressed air up to 10 bar.
Performance and Specifications
The operating principle is simple and highly reliable: as a normally closed (NC) solenoid, the valve blocks flow completely when de-energised. When powered by 220V AC, the coil generates a magnetic field that lifts the internal piston, allowing fluid to pass through a 20 mm orifice. Its wide thermal range — from -5°C to 100°C — makes it an excellent choice for everything from garden irrigation to residential heating circuits.

Frequently Asked Questions
Can this be used for hot water in a heating system?
Yes. It is rated for temperatures up to 100°C, making it perfectly suitable for hot water circuits in residential or light commercial heating installations.
What happens if there is a power cut?
The valve is normally closed, so it will shut off automatically if power is lost. The flow remains blocked until power is restored, preventing any uncontrolled leaks.
Is it compatible with compressed air?
Yes, provided the pressure does not exceed 1 MPa (10 bar). This device is engineered to handle both water and air applications.
Is it suitable for automated irrigation systems with timers?
Absolutely. It is designed to be connected to a 220V timer or controller, allowing you to automate your watering schedule without manual intervention.
Does the installation orientation matter?
Yes. Always follow the arrow on the valve body to ensure the correct flow direction. For optimal performance and longevity, mount the coil vertically with the head facing upwards.
