Have you ever wanted to control the flow of a liquid using your computer or microcontroller, but didn't know how? Well, here's how: The 12V solenoid controlled fluid valve. Simply connect a fluid source to the 3/4" threaded inlet and it will interrupt the flow until 12V is applied to the fast-on connectors on the solenoid.

We (nicegear) did a test fit on these and they will work fine on a standard NZ garden hose fitting.

Note: This is not a gravity-feed solenoid. This means that you will need enough water pressure to fully open the valve. Check the datasheet below for exact details. It operates at a minimum of around 3 PSI, allowing around 3 L/min of flow. Although the datasheet shows the valve working at 220 VAC, it's actually 12 VDC. Our 350 GPH pump does not have enough pressure for this valve. A garden hose or other pressurized system should work just fine.

  1. Hi! I paid $ 60 for 4pc 12V Solenoid Valve - 3 / 4 "why are not the product arrived in Norway?.

  2. Hi Alf,

    We cancelled your order and refunded the credit card used as we don't ship outside New Zealand.

  3. Hi. Will this solenoid valve work on 24V? (or vice versa, will the relay work with 12V output)
    I would like to interface it with the solid state relay: https://nicegear.co.nz/electronics-gear/solid-state-relay-ssr/

  4. Hi George,

    I believe they will work at 24V but we haven't tested that here. You want the DC SSR;


    Which certainly works fine at 12V so you can use that and this solenoid valve together fine - we've done it before many times.

  5. Wait, ignore that post - found the solution! :)

  6. Hi there, do you know if these are latching or not? Also, what is the current draw on these (preferably inrush + steady state)?


  7. Hi Glen,

    These ones are non-latching. Continuous current is around 300mA @ 12V, I don't have any inrush data right now.


  8. Hi Hadley,

    You mention 300mA as the continuous current - is that from a measurement? Spec sheet says the coil should have 4.75 +- 0.25 kOhm resistance, which would imply 2.7mA of current at 12v - 100 times less. At 300mA it would be using 3.6W of power, compared to only 32mW for the coil resistance on the spec sheet.


  9. Hi Tim,

    Yes I measured it here on my bench supply. I've just done it again and this one was 320mA @ 12V and 630mA @ 24V


  10. Hi,
    The spec sheet states 1/2"BSP inlet and 12mm outlet for the AQT15SP, but your product description states 3/4" threaded inlet, which is it?
