AMPEREUS A3-7IRU-ZZN0 AC220V Water/Air Closed Brass Electric Solenoid Valve, 1/2 Inch

Great performance, very reliable and efficient

It serves the purpose. I have used other such products. All get very hot even if used for 10 mins. This product also get hot but lesser than others. Installation is easy. There is no leakage in NC(normally closed) state.

Working well.

Best smart valve

Not reliable:( doesn’t stop the flow of water even during power off mode .. constantly leaks causing distress situations.. not recommended at all

Out of the five units I received, only three are working properly, while two appear to be defective. The faulty ones make a sound when connected to power, indicating they’re receiving electricity, but they fail to stop the flow as intended. Initially, I tested all solenoids only by powering them on and listening for the activation sound. Unfortunately, this method was not sufficient to confirm full functionality. By the time I discovered the issue, the return window had already closed. I recommend testing each solenoid with an actual water or air supply to ensure they operate correctly. The three functioning units are working as expected.

Installed the item in a automated system of watering of plants. Working very well.
