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

It is working perfectly till now. I am using it for water pipe line for my RO water tank and it will be turned on when the motor starts. Only price is little bit higher than the usual.

This device works well, but the water pressure seems to be a bit lower - but have to test more thoroughly I was thinking the device would open a valve when powered on - in a manner where the inlet and outlet are directly connected and one can see through it - but it is not so - it has an indirect path which is what I think reduces the water pressure. So if you are trying to use it near your water supply from municipal lines - you may need to check the water pressure reduction first before buying. Otherwise I think you can use it.

Great performance, very reliable and efficient

Best smart valve

Verry Good product but price are hai good quality.

Working well.

Product not good. I bought this product on 23rd March, 2025and it has failed on 11th November. 2025So not even six months it has worked.

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.
